Introduction：
胶原酶Ⅳ包含至少7中蛋白酶成分，分子量从68-130KD不等。它能消化多种组织胶原蛋白酶，来源于溶组织梭菌。
胶原酶Ⅳ包含至少7种蛋白酶成分，分子量从68-130KD不等。它能消化多种组织。胶原酶的使 用浓度一般为0.1- 5 mg/ml，消化过程中可以搅拌以促进酶的消化。胶原酶在消化的过程中可以引起 细胞的少量死亡，一般消化时间为15min至数小时。如果浓度发生变化那么消化时间可能更长。消 化过程中首选的缓冲液为含钙离子和BSA的Krebs Ringer Buffer。在消化的过程中如果细胞大量死亡 则需要降低酶量，同时可以加入0.5%BSA或5-10%血清来稳定细胞的状态和消化效果。 胶原酶的灭菌首先离心或者用0.8µm的滤器去掉不溶物。然后再用0.2µm的滤器过滤除菌。盐酸 苯甲脒和TLCK联合作用可以与该酶成分中大部分的蛋白酶结合而抑制其活性，但是他们却不会抑 制胶原酶的活性。其中盐酸苯甲脒的浓度一般为1 mM，TLCK 的浓度一般为0.100-0.135 mM。值得 注意的是两者不能完全保证所有蛋白酶的活性均被抑制。

酶的溶解性：0.05 - 0.1 mg/ml 胶原酶溶于50 mM TES buffer，pH 7.4 (37 ℃) 含 0.36 mM 氯化 钙。反应体系的终浓度为50 mM TES，0.36 mM 氯化钙，25 mg 胶原，0.005-0.01 mg 胶原酶。

酶液在含有 0.3-0.5 mM 钙离子 PH  7.5 的条件下可以在 37 ℃维持活性 5 小时。在-20℃可以维 持数月。
