应用
该产品适用于人类肿瘤,小鼠肾脏,人类成人和胎儿的脑、肺和许多其他上皮组织的解聚。 它还被证明适用于肝脏和肾脏灌注研究、胰腺消化、非实质性大鼠肝细胞的分离、以及肝细胞制备。 胶原酶也已用于制备动脉组织,以对晚期糖基化终产物进行研究。 该酶用于(浓度约为1mg/ml)对肝细胞的释放进行检测。 消化浓度范围为0.1至5mg/mL。
生化/生理作用
胶原酶产物是 C. histolyticum分泌的酶混合物,可通过分泌酶中10-18个组分的相对比率来区分不同的产物。 其主要成分是两种胶原酶、梭菌蛋白酶、和一种中性蛋白酶。 这些酶的协同作用可降解胶原蛋白和其他细胞内物质。胶原酶和中性蛋白酶的作用对于从组织中有效释放细胞是必需的。 各种类型的胶原蛋白都是胶原酶的天然底物。
每摩尔胶原蛋白酶被4g原子钙活化。 它被乙二醇-双(β-氨基乙基醚)-N,NN′,N′-四乙酸,β-巯基乙醇、谷胱甘肽、巯基乙酸和8-羟基喹啉抑制。
注意
以原包装形式,该产品在-20°C下可稳定保存一年。在37℃、50℃和-20℃下30天内,FALGPA或蛋白酶活性没有损失。如果分液(10mg/mL)形式快速冷冻并且在-20℃下冷冻保存,粗胶原酶的溶液可保持稳定。进一步的冻融步骤会破坏溶液稳定性。 当在冰上保持时,该产品可在7小时内保持100%活性。
单位定义
