胶原酶已用于制备研究晚期糖基化终产物（AGE）的动脉组织。该酶还与其他蛋白酶一起用于人肿瘤、小鼠肾、人脑、肺上皮和许多其他组织的解聚。它在肝脏和肾脏灌注研究、胰腺消化和非实质肝细胞的分离中也是有效的。 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.

从组织中有效释放细胞需要胶原酶和中性蛋白酶的共同作用。胶原酶被4克原子钙（Ca 2+ ）/摩尔的酶活化。培养滤液至少含有7种分子量为68-130kDa的不同蛋白酶。最佳pH范围为6.3-8.8。该酶识别序列 -R-Pro-8-X-Gly-Pro-R-，其中X通常是中性氨基酸。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。
