 wako低聚果糖标准品套装 蔗果三糖、四糖、五糖

      许多植物储存碳水化合物以菊糖形式或者淀粉形式。菊糖是以β(2-1)键连接果糖形成典型的末端葡萄糖结构。天然的菊糖包含一系列结构，聚合度从3到60。低聚果糖由菊糖水解得到，具有小店聚合度。低聚果糖通过GFn(Glucose and Fructose数目)。

低聚果糖是一种益生元，有益于人体健康。低聚果糖是一种天然活性物质。甜度为蔗糖的0.3-0.5倍。

       果聚糖广泛应用于农产品工业，菊糖和低聚果糖用于脂肪和糖，减少食品热量，比如冰淇淋、乳制品、糖果和烘焙食品。

低聚果糖标准品套装
低聚果糖是指2～5个果糖基为链节，以一个葡萄糖基为链的端基，以果糖基→果糖连接键为 主体骨架连结形成的碳水化合物。即是指1～4个果糖基以β-2，1键连接在蔗糖的D-果糖基上而形成的蔗果三糖（GF2）、蔗果四糖（GF3）、蔗果五糖（GF4）和蔗果六糖（GF5）的混合物。
低聚果糖是一种天然活性物质。甜度为蔗糖的0.3-0.6倍。既保持了蔗糖的纯正甜味性质，又比蔗糖甜味清爽。是具有调节肠道菌群，增殖双歧杆菌，促进钙的吸收，调节血脂，免疫调节，抗龋齿等保健功能的新型甜味剂，被誉为继抗生素时代后最具潜力的新一代添加剂——促生物质；在法国被称为原生素（PPE），已在乳制品、乳酸菌饮料、固体饮料、糖果、饼干、面包、果冻、泠饮等多种食品中应用。目前低聚果糖产品在日本、韩国、欧美国家及台湾地区已得到广泛应用，中国也与2009年推出了低聚果糖的国家标准

发表于由

Megazyme中文站-经销爱尔兰MEGAZYME试剂盒、酶标准品、糖酶片剂

淀粉总量HK检测试剂盒 MEGAZYME 淀粉总量HK检测试剂盒 K-TSHK
英文名： Total Starch HK Assay Kit
货号：K-TSHK
规格：100 assays per kit
市场价： 4208元
A modification of AOAC Method 996.11 AACC Method 76-13.01 RACI Standard Method for the measurement and analysis of total starch in cereal flours and food products. This kit contains an improved α-amylase that allows the amylase incubations to be performed at pH 5.0 (as well as pH 7.0). The method has been further modified by adjusting the D-glucose determination to a hexokinase/glucose-6-phosphate dehydrogenase/NADP+ based format.
UV-method for the determination of Total Starch in grains,
animal feeds, foodstuffs and other materials
Principle:
(α-amylase, 100°C + DMSO)
(1) Starch granules + H2O → maltodextrins
(amyloglucosidase)
(2) Maltodextrins + H2O → D-glucose
(hexokinase)
(3) D-Glucose + ATP → G-6-P + ADP
(glucose-6-phosphate dehydrogenase)
(4) G-6-P + NADP+ → gluconate-6-phosphate + NADPH + H+
Kit size: 100 assays
Method: Spectrophotometric at 340 nm
Total assay time: ~ 90 min
Detection limit: 1-100% of sample weight
Application examples:
Cereal flours, food products and other materials
Method recognition:
AOAC (Method 996.11), AACC (Method 76-13.01), ICC (Standard
Method No. 168), and RACI (Standard Method)
Advantages

  • Very competitive price (cost per test)
  • All reagents stable for > 2 years after preparation
  • Simple format

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.

Vectorlabs中国代理商 生物素-亲和素试剂 凝集素产品

Vectorlabs中国代理商 生物素-亲和素试剂 凝集素产品
vectorlabs，公司成立时，那时市面上还没有单克隆抗体、生物素-亲和素产品以及凝集素产品。1976, Vectorlabs率先纯化出凝集素产品，并迅速成为世界上该类产品的主要供应商。次年，Vetorlabs推出了生物素-亲和素系统。由于生物素和亲和素分子间极强的相互作用力，因此可以在生物素化的分子和结合有标记分子的亲和素间形成近似共价键的连接。
Vectorlabs最先向科研人员推出第一款生物素-亲和素试剂。首款试剂包括生物素化的蛋白和亲和素结合物，开启了检测方法的新纪元。Vectorlabs的生物素化抗小鼠免疫球蛋白和标记亲和素是检测和鉴定单克隆抗体使用最广泛的试剂。几年后，其他一些公司在认识到生物素-亲和素系统重要性后，也相继推出各自的产品。20年前，Vetorlabs开发了亲和素/链亲和素和生物素化的酶复合物，并申请专利，命名为”ABC“。这一成就也奠定了 VECTASTAIN®ABC 家族产品的基础。
相较于其他检测系统组织染色微弱或扩散染色以及需要高浓度一抗等问题，VECTASTAIN®ABC 系统组织染色较深、清晰、无背景染色，而且仅需低浓度的一抗。经过多年的优化改进，继而开发出VECTASTAIN®Elite ABC家族产品 – 该家族产品被广泛认可为最灵敏、最可靠、最经济的基于过氧化物酶的检测系统。后来，Vectorlabs又推出 ImmPRESS™ 试剂。这些试剂不是基于生物素-亲和素技术，而依赖于将过氧化物酶/碱性磷酸酶多聚物”micropolymers” 直接结合到二抗试剂。
Vectorlabs可提供

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.
Measured pH range of kit is 3 to 9 at 25°C
