来自组织溶梭菌的胶原酶已被用于： 诱发小鼠脑出血（ICH）消化3D胶原蛋白凝胶以进行免疫荧光分析引起小鼠局灶性血液外渗和出血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。该酶还与其他蛋白酶一起使用，用于人体肿瘤、小鼠肾、人脑、肺上皮等多种组织的解聚。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。 Collagenase from Clostridium histolyticum has been used: to induce intracerebral hemorrhage (ICH) in mice to digest collagen 3D gels for immunofluorescence to cause focal blood extravasation and hemorrhage in mouse 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.

组织溶梭菌包含两类胶原酶。梭菌胶原酶比哺乳动物胶原酶更高效。它在胶原三螺旋中的多个裂解位点进行裂解。梭菌胶原酶可参与气体坏疽中的细菌入侵。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。
