Analysis Note
还含有梭菌蛋白酶和非特异性中性蛋白酶活性。
Application
胶原酶与蛋白酶抑制剂已被用于一项评估免疫系统基因多态性与数量特征关系的研究。它也被用于研究 溶组织梭菌 胶原酶抑制剂的定量构效关系。sigma 酶已用于猪胰岛的分离。它也用于分离小鼠胰腺浸润的淋巴细胞。
Biochem/physiol Actions
有效地从组织中释放细胞需要胶原酶和中性蛋白酶的共同操作。每摩尔酶中 4 克钙 (Ca 2+) 可激活胶原酶。培养滤液被认为含有至少 7 种不同的蛋白酶，分子量范围为 68-130 kDa。最佳 pH 值为 6.3-8.8。这种酶通常用于消化组织样本中的连接成分，以释放单个细胞。胶原酶处理可使部分细胞死亡。通常使用 0.1 至 5 mg/mL 的浓度进行消化。反应持续时间可从 15 min 至数小时不等，以获得满意的细胞解离，而不会引起太多的细胞死亡。活性需要 Zn 2+。如果胶原酶不需要明显的蛋白酶活性，则使用本品。
Other Notes
所选批次的胶原酶 XI 与蛋白酶抑制剂混合，以限制胰腺组织中的胰蛋白酶活性。该制剂是通过与多个外部实验室合作开发的。

实验方案
To measure collagenase activity, N-(3-[2-Furyl]acryloyl)-Leu-Gly-Pro-Ala is used in a continuous spectrophotometric rate determination at 345 nm. Collagenase hydrolyzes collagen peptide bonds.
在测定胶原酶活性时，使用N-（3-[2-呋喃基]丙烯酰基）-Leu-Gly-Pro-Ala在345nm处进行连续分光光度法测定。胶原酶水解胶原肽键。
