纤维素酶检测试剂盒

纤维素酶检测试剂盒[CellG5法], Cellulase Assay Kit (CellG5 Method)

货号:K-CellG5

规格2:K-CellG5-2V 60/120次(手工)/240次(自动分析仪)
说明:CellG5检测试剂盒用于检测纤维素内切酶(1,4 -β-葡聚糖内切酶)包含两种组分:1) 4,6-O-(3-Ketobutylidene)-4-nitrophenyl-β-D-cellopentaoside (BPNPG5) 和 2)热稳定的β-葡萄糖苷酶。 酮阻断基团可阻止β-葡萄糖苷酶对BPNPG5的水解。通过纤维素内切酶的培养可生成非阻断的显色寡糖,被β-葡萄糖苷酶迅速水解。产生4-硝基苯酚的速率与β-葡萄糖苷酶水解BPNPG5直接相关。加入Tris缓冲液(pH 9.0)后可终止反应,并形成苯酚显色产物。
CellG5检测法代表了代表了纤维素酶测量方法的巨大进步。传统的纤维素酶检测依赖于酶底物,例如羧甲基纤维素,微晶纤维素,纤维低聚糖,CMC滤纸,染色多糖,包括CMC刚果红或纤维素天青。
