胶原酶已用于动脉组织的制备，用于晚期糖基化终产物 (AGE) 的研究。这种酶还与其他蛋白酶一起用于人类肿瘤、小鼠肾、人脑、肺上皮和许多其他组织的解聚。在肝脏和肾脏灌注研究、胰腺的消化和非实质肝细胞的分离中也有效。也适用于大鼠附睾脂肪垫脂肪细胞的制备。 Collagenase has been used in the preparation of arterial tissue for the study of Advanced Glycosylation End Products (AGE). The enzyme has also been used along with other proteases for the disaggregation of human tumor, mouse kidney, human brain, lung epithelium and many other tissues. It is also effective in liver and kidney perfusion studies, digestion of pancreas, and isolation of nonparenchymal hepatocytes. It is also suitable for the preparation adipocytes from epididymal fat pads of rats.

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作用。每摩尔酶用 4 克原子钙 (Ca 2+ ) 激活胶原酶。一般认为培养滤液至少含有 7 种不同的蛋白酶，分子量范围为 68-130 kDa（最适用 pH：6.3-8.8）。该酶识别序列-R-Pro-8-X-Gly-Pro-R-，其中 X 是最常见的中性氨基酸。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。
