Description

Solubility & Stability Screen is designed to assist in the identification of solution conditions which promote protein solubility and stability, and minimize protein precipitation. Solubility & Stability Screen is a solubility screen, a stability screen, and may also be used as an additive screen in the presence of a crystallization reagent.
The Hampton Research Solubility and Stability Screen can evaluate protein solubility, stability and crystallization in the presence of 94 different chemical additives sampling 17 different classes of reagents plus two controls.
Protein solubility and stability are universally required in a wide range of applications, including general biochemical studies, the preparation of proteins in pharmaceuticals, structural biology and crystallization.1-11The preparation of a concentrated, soluble and stable protein sample can often be a difficult task as proteins often aggregate, precipitate or denature.
Thermofluor (also known as Differential Scanning Fluorimetry, DSF and Protein Thermal Shift) provides a rapid, convenient and effective means of identifying subsaturating solution conditions that may also correlate with protein heterogeneity and poor crystallization outcomes.12
Protein solubility and stability is affected by many different chemical factors including pH, buffer type, chemical additives and excipients. pH and buffer type are dominant protein solubility and stability variables and can be evaluated and optimized using the Hampton Research Slice pH kit HR2-070. Slice pH evaluates protein solubility, stability and crystallization versus 20 different buffers over the pH range 3.5-9.6. Chemical additives influencing protein solubility and stability can be evaluated using the Solubility & Stability Screen.
It is widely accepted that protein solubility and stability can be increased by the use of chemical additives.5,15Seventeen classes of reagents are sampled by the Solubility & Stability Screen and each of these classes has been reported as important in improving sample solubility and stability.2-11
The Solubility & Stability Screen is a set of 94 high purity reagents formulated in high purity water (NCCLS/ASTM Type 1+) at 25°C and are 0.22 micron sterile filtered. The 94 solubility and stability reagents are formulated at 2 to 10 times their recommended working concentration. The remaining two reagents are water and a negative (TCA) control. A water control demonstrates the effect of diluting sample as well as sample buffer concentration. TCA, the negative control, demonstrates total sample precipitation, loss of sample solubility and loss of sample stability. The effects of the Solubility & Stability reagents can be compared with this negative control to assist in the identification of reagents promoting sample solubility and stability. 500 microliters of each reagent is supplied in a sterile 96 well polypropylene Deep Well block. The Solubility & Stability Screen reagents are compatible with the sitting or hanging drop vapor diffusion, microbatch, free interface diffusion, sandwich drop vapor diffusion, and dialysis crystallization methods utilizing water soluble reagents.

Applications
  Primary or secondary, polymer, salt and pH matrix crystallization screen for biological macromolecules
Features

Developed at Hampton Research
PEG/Ion is a sparse matrix profile of anions and cations in the presence of monodisperse Polyethylene glycol 3,350 over pH 4.5 – 9.2
PEG/Ion 2 screens a complete profile of titrated organic acids at varying pH levels (3.7 – 8.8) in the presence of monodisperse PEG 3,350
PEG/Ion HT combines PEG/Ion and PEG/Ion 2 in a single 96 Deep Well block
 Description

PEG/Ion, developed by Hampton Research, is a crystallization screen designed to evaluate monodisperse, high purity Polyethylene glycol 3,350 and 48 unique salts representing a very complete range of anions and cations frequently used in the crystallization of biological macromolecules. The primary screening variables are PEG, ion type, ionic strength, and pH. More than 60% of the published crystallizations utilized PEG as a primary crystallization reagent and in approximately 50% of those reports, the PEG was combined with an ion as a secondary crystallization reagent. PEG/Ion reagents are formulated without a buffer and are not pH titrated.
PEG/Ion 2 is an extension to the fundamental crystallization strategy in PEG/Ion. PEG/Ion 2 reagents cover the monodisperse, high purity Polyethylene glycol 3,350 and an array of neutralized and pH adjusted organic acids, multivalent ions, a novel Citrate BIS-TRIS propane buffer system and pH (4 – 8.8). The formulation of PEG/Ion 2 was developed at Hampton Research. Each of the 48 reagents in PEG/Ion 2 contains PEG 3,350 as the polymer (precipitant). The concentration of PEG is varied from 12% w/v to 20% w/v depending upon the type and concentration of buffer/salt paired with the polymer. Thirteen of the forty-eight PEG/Ion 2 reagents contain a separate buffer component. The remaining PEG/Ion 2 reagents are buffered by the titrated organic acid salt. Six of these thirteen conditions feature a novel Citric acid BIS-TRIS propane (CBTP) buffer. The CBTP buffer uses Citric acid and BIS-TRIS propane as the acid base pair to create a two component buffer system effective across pH 2.5 to 9.5. The ratio of Citric acid to BIS-TRIS propane determines the solution pH. Thirty-five of the forty-eight PEG/Ion 2 reagents contain a neutralized or pH adjusted organic acid in the presence of the polymer. Neutralized organic acids are highly effective crystallization salts.1 Four PEG/Ion 2 reagents feature polyvalent cations. Two of these reagents contain cation mixes, saving sample by screening six different cations with only two reagents. Tryptone, a casein digest combinatorial library of peptides, is included in PEG/Ion 2. PEG/Ion 2 reagents 1-30, 42, 45-47 are formulated without a buffer and are not pH titrated.
PEG/Ion contains 48 unique reagents, 10 ml each.
PEG/Ion 2 contains 48 unique reagents, 10 ml each.
PEG/Ion HT contains 1 ml of each reagent from PEG/Ion and PEG/Ion 2 in a single Deep Well block format.
Ready-to-use reagents are sterile filtered and formulated with ultra-pure Type 1 water, using the highest purity salts, polymers, organics and buffers. Individual reagents are available through the Hampton Research Custom Shop.

Description
MRC Maxi 48-Well Crystallization Plate for Automated Optimization
The MRC Maxi optimization plate is a breakthrough for macromolecular crystallization presented in a 48 well format. Offering easy to automate crystallization optimization with large sitting-drops, the new MRC Maxi Crystallization plate is the perfect solution. Manufactured by Swissci AG, the plate offers an SBS format while providing 48 wells. MRC Maxi is intended for large drops and is compatible both with standard robotic systems as well as manual pipetting.
The plate was developed at the MRC Laboratory of Molecular Biology (Cambridge, UK) in collaboration with Jan Löwe and Fabrice Gorrec. It is a result of many years of experience in successful robotic high-throughput crystallization and complements the original MRC crystallization plate, which is intended for smaller drop volumes and higher throughput during screening.
Drop volumes of up to 10 µl are possible. The 9 mm standard distance between wells is preserved, enabling the use of multi-channel manual pipettes and robotic liquid handlers, making MRC Maxi one of the most automation-friendly optimization plates on the market.
MRC Maxi is covered by global intellectual property and design registration as are the Swissci AG MRC 2 lens 96 well plates. Several breakthrough features of the original MRC plate have been maintained. Wells are labeled individually. Drops are raised for easy access during crystal retrieval. MRC Maxi uses the same proprietary polymer specially selected for the purpose of UV light visualization and the material used keeps through-plastic evaporation to a minimum. Well shapes are spherical but shallow.
The MRC Maxi Crystallization plate offers unique properties that make it the ideal choice for microliter-sized optimization experiments and is made from UV compatible UVP.
The advantages of the MRC Maxi Crystallization plate – in brief

  Sparse matrix formula efficiently samples salts, polymers, organics and pH
  pH range 4.6 – 8.5

Description
MembFac is a highly effective sparse matrix screen specifically designed as a preliminary screen for the crystallization of membrane proteins. MembFac is based upon the highly effective biased sparse matrix methodology. The MembFac screen matrix is optimized for the crystallization of membrane proteins.
MembFac contains 48 unique reagent formulations. With this set of 48 conditions, numerous chemicals and chemical combinations are utilized, allowing one to evaluate a large variety of potential crystallization conditions. MembFac covers a broad pH range between 4 and 9.
The Rationale
The basic rationale of MembFac is to perform a sparse matrix screen while changing the detergent dimension because detergents play an important factor in the crystallization of membrane proteins. A MembFac screen is to be completed for each detergent. Detergent screens are available separately.
The Method
The membrane protein of interest is first isolated in the detergent which gives the highest stability and activity. The protein concentration should be approximately 10 to 20 mg/ml and the detergent concentration should be only slightly above the CMC. The sample is then set against MembFac, using all 48 solutions plus the screening detergent(s) of choice. The screening detergent concentration should be approximately one to three times the CMC. Hence, for each detergent screened, one would utilize approximately 1 to 2 mg of sample.
The MembFac protocol was used to crystallize membrane proteins including SQR, fumerate: quinone oxireductase, LHII, and LHCII.
Crystal Screen Lite is a sparse matrix of trial crystallization reagent conditions based upon the Crystal Screen™.3 The primary screen variables are salt, pH, and precipitant (salts, polymers, volatile organics, and non-volatile organics).2Crystal Screen Lite differs from the original Crystal Screen kit in that the primary precipitant reagents are one-half the concentration of that used in the original Crystal Screen formulation. The secondary salts, ions, and buffers remain at the original Crystal Screen concentration. Reducing the primary concentration of the primary precipitant results in a screen which is “more gentle” on the sample and typically produces much less precipitate conditions than the original Crystal Screen.
MembFac contains 48 unique reagents, 10 ml each.
MembFac HT contains 1 ml each of all 48 reagents from MembFac and reagents 1-48 from Crystal Screen Lite in a single Deep Well block format.
Ready-to-use reagents are sterile filtered and formulated with ultra-pure Type 1 water, using the highest purity salts, polymers, organics and buffers. Individual reagents are available through the Hampton Research Custom Shop.

Description
The Crystal Screen and Crystal Screen 2 reagent kits are designed to provide a highly effective and rapid screening method for the crystallization of macromolecules. The screens are simple and practical for finding initial crystallization conditions. The initial crystallization conditions for more than 1,000 proteins, peptides, oligonucleotides, and small molecules have been determined using Crystal Screen.
A highly effective approach to overcome the exhaustive search for suitable crystallization conditions is the use of a sparse matrix method of trial conditions that is biased and selected from known crystallization conditions for macromolecules. The formulation utilized in Crystal Screen and Crystal Screen 2 evaluates 96 unique mixtures of pH, salts, polymers and organics, and their ability to promote crystal growth.
Crystal Screen contains 50 unique reagents, 10 ml each and is based on the sparse matrix formulation first described by Jancarik and Kim in 1991.
Crystal Screen 2, an extension of Crystal Screen, contains 48 unique reagents, 10 ml each and is based on the formulation first described by Cudney et al in 1994.
Crystal Screen HT contains 1 ml each of reagents 1-48 from Crystal Screen and all 48 reagents from Crystal Screen 2 in a single Deep Well block format.
Ready-to-use reagents are sterile filtered and formulated with ultra-pure Type 1 water, using the highest purity salts, polymers, organics and buffers. Individual reagents are available through the Hampton Research Custom Shop.

 Description
SaltRx was developed by Hampton Research as a primary and secondary, salt and pH based crystallization screen for biological macromolecules. Salt is the only primary crystallization reagent (precipitant) utilized. Based on a design of 96 conditions, the screen evaluates a broad portfolio of crystallization salts of varying concentration and pH. The selection, concentration, and pH of the salts were determined by data mining the BMCD1 and other crystallization databases, crystallization reports in the literature, and internal crystallization trials performed at Hampton Research. Based on this analysis, up to 35% of protein crystallizations involve salt as the primary crystallization reagent. SaltRx can be used as a primary crystallization screen when salt, ionic strength and pH are desired or suspected as appropriate crystallization variables. It is also useful as a secondary screen when salt only reagents/conditions from screens such as Index™, Crystal Screen™, and Grid Screen™ produce crystals and when further screening for additional salt conditions or optimization is desired. Since this screen does not contain volatile organics, it is compatible with microbatch, vapor diffusion, liquid and gel diffusion crystallization methods. SaltRx may also be used for dialysis crystallization in conjunction with Dialysis Buttons™.The original SaltRx kit (HR2-108) contained 96 unique reagents, 10 ml each. This kit has been discontinued and converted into two 48 reagent based kits, SaltRx 1 and SaltRx 2, available separately, which when used together are identical to the original SaltRx.SaltRx 1 contains 48 unique reagents, 10 ml each. SaltRx 1 contains reagents 1-48 of the original SaltRx 96 reagent kit.Salt Rx 2 contains 48 unique reagents, 10 ml each. SaltRx 2 contains reagent 49-96 of the original SaltRx 96 reagent kit.SaltRx HT contains the 96 SaltRx 1 and SaltRx 2 reagents in a single Deep Well block format.Ready-to-use reagents are sterile filtered and formulated with ultra-pure Type 1 water, using the highest purity salts, polymers, organics and buffers.

Hampton Natrix • Natrix 2 • Natrix HT

Applications
  Primary biased sparse matrix crystallization screen for nucleic acids & protein/nucleic acid complexes  主要用于核酸和蛋白质/核酸复合物的删选
Features

Nucleic acid sparse matrix screen
Sparse matrix formulation efficiently samples salts, polyols, polymers, organics, additives & pH
pH range 5.6 – 8.5
Tube or Deep Well block format
 Description
Natrix, Natrix 2 and Natrix HT are based upon published reagent formulations for the crystallization of nucleic acids and protein-nucleic acid complexes. A variety of hammerhead ribozymes and other ribozymes, RNAs, DNAs, RNA-drug complexes, and RNA-protein complexes have been crystallized using the Natrix protocols.By using sparse matrix sampling technology, The Natrix kits allow one to quickly test wide ranges of pH, salts, and precipitants using a very small sample of nucleic acid.
Natrix screens are unique in that rather than relying solely on the traditional nucleic acid precipitant MPD, Natrix screens also utilize Polyethylene glycols (PEGs) in a variety of molecular weights (200, 400, 4,000, 8,000) as well as 2-Propanol, Polyethylene glycol monomethyl ether (PEG MME), and 1,6-Hexanediol. Many of the polymeric and low molecular weight organic precipitants are combined with various monovalent salts as precipitating agents. This combination of salts and low molecular weight organics and polyalcohols, as well as the utilization of varying chain length PEGs, has proven to be a successful combination for producing nucleic acid and protein-nucleic acid complex crystals.
Natrix contains 48 unique reagents, 10 ml each and is based on the sparse matrix formulation first described by William Scott in 1995.
Natrix 2, an extension of Natrix, contains 48 unique reagents, 10 ml each. Natrix 2 is a biased sparse matrix screen based on extracting patterns from crystallization data as well as reagent formulations first described by Berger et al in 1996.
Natrix HT contains 1 ml of each reagent from Natrix and Natrix 2 in a single Deep Well block format.
Ready-to-use reagents are sterile filtered and formulated with ultra-pure Type 1 water, using the highest purity salts, polymers, organics and buffers. Individual reagents are available through the Hampton Research Custom Shop.

Hampton蛋白质结晶捞针(结晶环)18 mm Mounted CryoLoop™

Hampton蛋白质结晶捞针(结晶环)18 mm Mounted CryoLoop™

Applications

Cryocrystallography
Features

Adjustable loop orientation
Synthetic CryoLoop on adjustable stainless steel MicroTube
MicroTube specially engineered with EasySnap notches
20 micron diameter nylon CryoLoop

Description
Similar to the Mounted CryoLoop™ in design and function, the Adjustable Mounted CryoLoop allows one to manipulate and orient the CryoLoop to multiple, unique positions previously unattainable with typical cryo setups. The Adjustable Mounted CryoLoop is a 20 micron diameter synthetic loop mounted inside a malleable stainless steel sleeve, which in turn, is mounted inside the EasySnap MicroTube™.
Using a specially designed L-shaped tool (HR5-902) with a positioning notch, one can manipulate the angle and orientation of the CryoLoop by bending and adjusting the angle of the malleable stainless steel insert which holds the CryoLoop. The Adjustable Mounted CryoLoop may be positioned several times. Note: Repeated manipulation will fatigue the sleeve which can lead to failure of the sleeve. The Adjustable Mounted CryoLoop is designed to work with the CrystalCap System components.
The MicroTube is 24 mm in length and is specially engineered with EasySnap™ notches at the 10, 12, 14, 18, and 21 mm measures. To obtain the desired length of MicroTube, simply snap the MicroTube at the desired length and stake it to the CrystalCap™ Magnetic or CrystalCap™ Copper Magnetic. These nylon loops show minimal diffraction, are thin for fast freezing, strong, and aerodynamic.
Most data collection geometries prefer or require a 22 mm length between the base of the cap and the beam. For a 22 mm overall length using the CrystalCap, CrystalCap ALS, CrystalCap ALS HT and CrystalCap SPINE HT, snap the MicroTube at the second notch from the bottom, creating an 18 mm MicrozTube lenghth and secure to the CrystalCap using epoxy or similar adhesive. For a 22 mm over length using the CrystalCap Copper, CrystalCap Copper HT, CrystalCap ALS Copper HT snap the MicroTube at the fifth notch from the bottom (notch closest to the CryoLoop) and secure to the CrystalCap using epoxy or similar adhesive.
The HR5-902 Tool for Adjustable Mounted CryoLoop is not included with the Adjustable Mounted CryoLoop and must be purchased as a separated item.

Spearlab FD-130 Cryogenic Foam Dewar (130 ml) – Mini : Small, hexagonal outside, hand held foam dewar, maximum volume 175 ml. Each dewar is supplied with a matching foam lid to insulate the contents from ambient air. Dimensions of the cylindrical cavity in this vessel are 2 inches in diameter by 3.5 inches deep, so that it easily holds 130 ml and a maximum volume of 175 ml of liquid nitrogen. The HR4-676 has an overall height of approximately 4.5 inches without cover and the width is 3.5 inches at the top and 3.75 inches on the bottom (measured on the flats of the hexagon). Circular cover is approximately 0.5 inches tall x 3.5 inches diameter.
Spearlab Cryogenic Foam Dewar (500 ml) – Small: The small foam dewar shape is circular, with a protruding handle, so that it resembles a large teardrop. Each dewar is supplied with a matching foam lid to insulate the contents from ambient air. Dimensions of the cylindrical cavity in this vessel are 4.5 inches in diameter by 2.8 inches deep, so that it easily holds 500 ml of liquid nitrogen.
Spearlab FD-800 Cryogenic Foam Dewar (800 ml) – Standard: The standard foam dewar shape is circular, with a protruding handle, so that it resembles a large teardrop. Each dewar is supplied with a matching foam lid to insulate the contents from ambient air. Dimensions of the cylindrical cavity in this vessel are 5.8 inches in diameter by 2.8 inches deep, so that it easily holds 800 ml of liquid nitrogen.
Spearlab FD-1400 Cryogenic Foam Dewar (1400 ml) – Large: The large foam dewar shape is circular, with a protruding handle, so that it resembles a large teardrop. Each dewar is supplied with a matching foam lid to insulate the contents from ambient air. Dimensions of the cylindrical cavity in this vessel are 6.3 inches in diameter by 3.8 inches deep, so that it easily holds 1400 ml of liquid nitrogen. Overall height is approximately 6 inches without cover and the width is 9 inches on the short axis and 11 inches on the long axis. Cover approximately 0.5 inches tall x 9 inches diameter.
Spearlab FD-1800 Cryogenic Foam Dewar (1800 ml) – Tall: The tall foam dewar shape is a tapered octagon on the outside with a cylindrical interior. The tapered octagon features a wide, stable base. Each dewar is supplied with a matching foam lid to insulate the contents from ambient air. Dimensions of the cylindrical cavity in this vessel are 3.5 inches in diameter by 12.5 inches deep, so that it holds approximately 1,800 ml of liquid nitrogen. The outside dimensions of the tall dewar are 15.25 inches tall with a 6.25 inches wide top and a 7.75 inches wide base (measured on the flats of the octagon). The cover is 6.5 inches in diameter and 0.5 inches thick.
The patented (USPTO # 7,971,744) design of the Spearlab Cryogenic Foam Dewar makes it easy to handle and safer to use than a traditional low profile glass dewar. Also, because of its lower thermal mass, a foam vessel will cause less boil off when it is filled with liquid nitrogen. Additionally, the dewar will accumulate less frost during regular use. The end result is that less liquid nitrogen is consumed.
The dewars are made from cross-linked polyethylene foam. A density of 4 pounds per cubic foot is used for the 130 ml and 800 ml dewars. A density of 2 pounds per foot is used for the 1400 ml and 2 liter dewars. The higher density foam has significantly higher mechanical strength and stiffness. The lower density foam has slightly lower thermal conductivity. Like most lightweight insulation materials, the thermal conductivity of the foam is predominantly determined by the thermal conductivity of air, which eventually permeates the pores of the foam material.

Description
Art Robbins Instruments has developed the ideal family of plates for crystallography applications: the Intelli-Plate. All versions of the Intelli-Plate have the SBS microplate footprint and standard well spacing and are ideal for manual or automated processing.
The Intelli-Plate 96-2 Low Profile (Art Robbins 102-0001-10 Hampton Research HR3-116 and HR3-117) is a low profile version of the Intelli-Plate 96-2 LVR (Low Volume Reservoir). Reservoir volume: 100 µl max. Drop well volume: 4 µl and 10 µl max. UV transmissible and low birefringence.
The CrystalMation Intelli-Plate 96-3 low-profile crystallization plate (Art Robbins 102-0001-13 Hampton Research HR3-118 and HR3-119) is a low profile version of the Intelli-Plate 96-3 LVR (Low Volume Reservoir). The plate is designed for sitting drop vapor diffusion crystallization experiments. It is constructed from optically clear, UV-transmissible, chemically resistant plastic with superior low birefringence. The low-profile construction allows for higher density in plate storage and imaging systems, maximizing your investment and valuable space. The plate is designed to be a substantial improvement in existing low-profile plates, allowing for superior sealing due to thicker well design and a flat sealing surface. It has been built to the SBS (Society for Biomolecular Screening) standard dimensions with 8 vertical wells along the left side of the plate (A-H) and 12 horizontal wells along the top of the plate (1-12). It is compatible with automated instrumentation including the CrystalMation line of instruments from Rigaku. The plate features three identical sized sample drop wells per reservoir. The wells are concave depressions along the left side (Y-axis) of the plate and are located on the ledge above the adjacent, flat bottom reagent reservoir. Each well features a round bottom for easy crystal harvesting and can hold up to 1 µl of sample. The multiple well design allows for combinatorial experiments, complex co-crystallization experiments for ligand screening, or for drop concentration variation. The reagent reservoir is typically filled with 50 to 70 µl of reagent. Reservoir volume: 100 µl max. Drop well volume: 1 µl max. UV transmissible and low birefringence.
The Intelli-Plate 96-2 LVR (Art Robbins 102-0001-00 Hampton Research HR3-143 and HR3-145) is a Low Volume Reservoir version of the original Intelli-Plate. Reservoir volume: 100 µl max. Drop well volume: 1 µl max. UV transmissible and low birefringence.
The Intelli-Plate 96-3 LVR (Art Robbins 102-0001-03 Hampton Research HR3-183 and HR3-185) is a Low Volume Reservoir, 3 drop well version of the Intelli-Plate. Reservoir volume: 100 µl max. Typical reservoir volume 50 µl. Drop well volume: 1 µl max. UV transmissible and low birefringence.
The Intelli-Plate 96-2 Original crystallization plate (Art Robbins 102-0011-00 Hampton Research HR3-297 and HR3-299) is an optically clear plate for sitting drop vapor diffusion crystallization. All wells have standard 9 mm spacing to conform to SBS standards with 8 vertical wells along the left side of the plate (A-H) and 12 horizontal wells along the top of the plate (1-12). This plate features two locations for sample per reservoir. The sample drop locations are located along the left side of the reagent reservoir, along the Y-axis of the plate. The sample wells are concave depressions on the ledge above the adjacent, flat bottom reagent reservoir. One sample well is located above the second sample well. The top sample well can hold 10 µl or less of sample. The lower sample well can hold 4 µl or less of sample. The reagent reservoir is typically filled with 100 µl of reagent and is capable of holding up to 300 µl of reagent. The sidewalls separating adjacent wells or reservoirs are 0.9 and 1.0 mm thick in order to offer a larger area for sealing the plate and a separation of the reservoirs. This plate is rigid, with virtually no torsional flex and is designed for either manual or automated pipetting. UV transmissible and low birefringence.
The Intelli-Plate Flat Shelf (Art Robbins 102-0001-01 Hampton Research HR8-171 and HR8-172) crystallization plate is a flat drop shelf version of the original Intelli-Plate. Reservoir volume: 300 µl max. No drop well. UV transmissible and low birefringence.
The Intelli-Plate 96-2 Shallow Well (Art Robbins 102-0001-20 Hampton Research HR3-163 and HR3-164) has two identically sized 2 µL reaction wells and a 140 µL screen reservoir. Each of the two identical well features a round bottom shallow well design for easy crystal harvesting and is arranged in an 8 x 12 array. This plate has low birefringence and is UV compatible. This plate is also available in a low profile height (Art Robbins 102-0001-21).
The plates can be sealed using Crystal Clear Sealing Film (HR3-609), 3 inch wide Crystal Clear Sealing Tape (HR4-506) or ClearSeal Film™ (HR4-521).
The height of Intelli-Plate is 0.560 inches. The height of Intelli-Plate Low Profile is 0.315 inches (8.001 mm).

The tools in the Wizard Cubic LCP (lipidic cubic phase) Kit enable researchers to prepare LCP-type crystallizations by hand. Ideal for low-protein experiments: effective protein volume for a single crystallization experiment is about 80 nanoliters. Wizard Cubic LCP Kit tools work especially well when traditional methods have failed to yield crystals. Lipidic cubic phase has worked well for the crystallization of 7TM membrane proteins (proteins with seven transmembrane helices). Four out of six GPCRs (G-protein coupled receptors), an important membrane protein class, and several microbial 7TM proteins have been crystallized using the LCP approach.
图片
CRYO (I、II)
The Wizard Cryo™ line of random sparse matrix screens is designed for scientists who want to avoid the additional step of optimizing a cryoprotectant condition. Every Wizard Cryo formulation flash-freezes to a clear, amorphous glass in liquid nitrogen or in a cryo-stream at 100K. Crystals can be frozen directly from their growth drops, avoiding the additional step of pre-equilibration with an artificial cryo-condition that can damage the crystal. Eleven different cryocrystallants and sparing use of glycerol ensures a broad sampling of possible cryo conditions. Choose from Wizard Cryo 1 or 2 formulations in tubes or Wizard Cryo 1 and 2 together in a 96-well matrix block.

The SWISSCI 3 Lens Crystallization Plate is an ideal product for protein crystallization presented in a 96-well plate format.
该结晶板是用于在96孔板呈现蛋白质结晶的理想产品
The plate was developed in collaboration with very experienced protein crystallographers. It is the result of many years of experience in successful robotic high-throughput crystallization and combines many of the necessary features not earlier available to the crystallographer.
该板协同经验非常丰富的蛋白质晶体学家开发。这是多年的成功的机器人高通量结晶经验的结果,并结合了许多不早提供给晶体学家必要的功能。
The SWISSCI 3 Lens crystallization Plate offers unique properties that make it ideal for both nanoliter crystallization screening and mircoliter optimization alike. Made from optically superior polymer (UVP) and with a new design of the wells, the plate allows easy crystal viewing and retrieval.The Advantages of the 3 Lens Crystallization Plate    优点:Easy crystal retrieval   易结晶
Raised wide wells make the crystal mounting especially easy.Easy viewing
The wells are a wide conical shape and have a lens effect for perfect illumination. The micro-numbering ensures you will never get lost again (visible by microscope). The optically superior polymer is UV transmissible and may be used to differentiate between salt and protein crystals.Better sealing
Wide partition walls between the wells give plenty of area for good sealing with tape. No central bending occurs in this very robust structure. Excellent long term storage – no sample evaporation.Wide range of volumes
Typical volumes are 20-40 µl of reservoir and 50 nl-5 µl drop size. The 288 optical wells offer three times the number of experimental constructions.ANSI/SLAS 1-2004 Standard
The plates are designed to the 96-well ANSI/SLAS 1-2004 standards for all common holders and external numbering (A-H, 1-12)with corner location make the plate easy to use in a robotic sampler. The 3 Lens plate is suitable for centrifugation. The unique 3 drop protein crystallization plate offers a new way of sitting-drop crystallography. The 288 wells are optically perfect designed to observe crystals under a microscope.3 Lens plate features
Easy to fill 96-lens structure – typically 30 microlitres per buffer lens. Standard ANSI/SLAS 1-2004 form for automation. Optically perfect wells with lens effect for a better view with microscope. Microscopic identifier within wells, simplifying the orientation under the microscope. Maximum volume of the buffer reservoir is 40 microlitres. Grown crystals are easy to identify and to remove from lens due to a low-binding polymer. Plate with 3 lenses for each sample, better growing security with triplicates or the ability to use lens two and lens three as mixing stations. Lenses fill without micro-droplets jumping out due to static effects. Wells can be individually sealed with a perfectly flat upper surface – there is a large land area designed to ensure integrity of each lens section. The profile allows for easier storage. Low volume buffer well enables savings on reagents. Triplicates allow for 288 constructs per plate.3 Well Midi Crystallization Plate (Swissci 3W96TUVP)

Description
Siliconized glass cover slides allow a droplet to be suspended in a position which provides near optimal conditions for vapor diffusion with the surrounding reservoir solution. These siliconized glass cover slides provide a consistent, high quality finish for crystallization experiments. The hydrophobic surface produces a drop which “stands well” and does not flatten on the glass. The siliconized surface prevents the adhesion of crystals and precipitate onto the glass surface. Use Dow Corning Vacuum Grease (HR3-510), Dow Corning 7 Release Compound (HR3-508), or immersion oil to seal cover slide to plate. Available in 12, 18 or 22 mm diameter circles and 22 mm diameter squares. Available in 0.22 mm or 0.96 mm glass thickness. The 0.96 mm thick slides are virtually unbreakable during crystallization handling.

Plain Glass Cover Slides
ApplicationsHanging, sitting or sandwich drop crystallization
Features
0.22 mm glass thickness
12 mm glass diameter
Hydrophilic glass surface
Circle & squareDescription
Plain, non-siliconized, hydrophilic glass cover slides. Useful for hanging drop, sitting drop, and sandwich drop vapor diffusion crystallization methods. The hydrophilic surface creates a drop which is more flat than a drop on a siliconized surface. This offers enhanced imaging for very small drops. Use Dow Corning® Vacuum Grease (HR3-510), Dow Corning® 7 Release Compound (HR3-508), or immersion oil to seal cover slide to plate.

CryoTong™ – Long
ApplicationsCrystal transfer under cryo temperature
FeaturesArtery clamp style closure30 seconds of cryo temperature180 mm length
Description
The CryoTong is a tool used to manually transfer a crystal mounted on a CrystalCap™ from liquid nitrogen to a magnetic base in a goniometer head positioned in a cryogenic stream, and then back to liquid nitrogen. The one-piece, compact CryoTong is available in two lengths. The long CryoTong is approximately 180 mm in overall length. The artery clamp style maintains the CryoTong in the closed position until the clamp is squeezed, which opens the opposing heads. The heads are non-magnetic stainless steel. The handle is magnetic stainless steel. The inside of the head is machined to closely surround the CrystalCap with loop and crystal in place. A small retaining lip is machined into the lower portion of the head to prevent the CrystalCap from slipping out of the CryoTong when the tool is in the closed position. The CryoTong can maintain the temperature of the crystal at -160°C for up to 30 seconds during room temperature crystal transfers. Choose the proper CryoTong size based upon the pin length required by the configuration of the x-ray data collection hardware used. The 18 mm CryoTong (HR5-112) is to be used with the CrystalCap HT and any other CrystalCap configured for 18 mm.HR5-114 Long CryoTong 18 mm, 180° features the head in alignment with the handle of the CryoTong.

Vial Clamp™ – Straight
ApplicationsVial support and manipulation
FeaturesStraight end tipHemostat style closureDescription
The Vial Clamp™ – Straight is a chrome plated, hemostat style tool. It has a tip shaped to hold the storage vial of all the CrystalCap Systems™ straight when the clamp is closed. The clamp can be locked using the hemostat style closure. This clamp makes it easy to dip the storage vial into liquid nitrogen for crystal storage. The complete length of the clamp is straight, with an overall length of 195 mm. When the vial is placed in the clamp, the length of it is positioned perpendicular, 90° to the length of the clamp.

CrystalWand™ Magnetic
ApplicationsCrystalCap Magnetic & CrystalCap Copper Magnetic handling toolDescription
The CrystalWand Magnetic is designed to be used exclusively with the CrystalCap Magnetic, CrystalCap Copper Magnetic, and CrystalCap HT systems during transfer of the caps from the vial to the goniometer head and from the goniometer to the vial. The 6 1/2” (165 mm) long chrome plated steel wand features a plastic housing enclosing a spring tensioned plunger that when depressed, moves a non-magnetic steel platform away from the magnet housed in the end of the wand. This causes the steel CrystalCap to detach from the wand and be placed readily into the vial or the CryoTong™. When the platform is retracted, the wand securely holds the steel CrystalCap Magnetic. The CrystalWand Magnetic 45° (McMiken Tool) offers the same functionality but is bent at a 45° angle at approximately 2.5 cm from the magnet end.HR4-729 CrystalWand Magnetic, StraightHR4-315 CrystalWand Magnetic, 45° (McMiken Tool)

Vial Clamp™ – Curved
ApplicationsVial support & manipulation
FeaturesCurved end tipHemostat style closureDescription
The Vial Clamp – Curved is a chrome plated, hemostat style tool. It has a tip shaped to hold the storage vial of all the CrystalCap Systems at an angle when the clamp is closed. The clamp can be locked using the hemostat style closure. The end of the clamp, where the vial is held, is curved at either a 45°/135° or 110°/ 70° angle. When the vial is placed in the clamp, the length of it is positioned to the clamp at either of those same angles. The overall length of each clamp is the same, 195 mm.HR4-671 Vial Clamp – Curved 45°/135°HR4-672 Vial Clamp – Curved 110°/70°

Description
Index is designed as a 96 reagent crystallization screen that combines the strategies of the grid, sparse matrix, and incomplete factorial screening with traditional, contemporary, and new crystallization reagent systems into a highly effective and efficient format.
Index, as the name implies, efficiently samples a series of specially formulated reagent zones to identify which reagent class or classes and pH are effective in producing crystals or limiting sample solubility. Results from Index can be used to design optimization experiments and to identify follow on screens by reagent class. For example, positive results with salt based reagents in Index may be followed up with further screening using SaltRx or Grid Screen Salt HT. Success with polymer based reagents in Index may be followed up with further screening using PEGRx or PEG/Ion.
Index utilizes a broad, yet refined portfolio of crystallization reagent systems. These include the following: (1) traditional salts such as Ammonium sulfate and Sodium chloride versus pH; (2) neutralized organic acids such as Sodium malonate and Tacsimate; (3) High salt concentration mixed with low polymer concentration as well as high polymer concentration mixed with low salt concentration and; (4) Low ionic strength using polymers such as PEG, MPD, Pentaerythritols versus pH. These reagent systems are formulated across a sparse matrix and incomplete factorial of concentration ranges, sampling a pH range of 3 to 9.
Index contains 96 unique reagents, 10 ml each.
Index HT contains 96 unique reagents in a single Deep Well block format.
Ready-to-use reagents are sterile filtered and formulated with ultra-pure Type 1 water, using the highest purity salts, polymers, organics and buffers. Individual reagents are available through the Hampton Research Custom Shop.
