Sigma collagenases are fully characterized by enzymatic activity. Many are specifically tested for suitability for cell dissociation and cell viability for hepatocytes, adipocytes, and pancreatic cells.
Unit Definition One collagen digestion unit (CDU) liberates peptides from collagen from bovine achilles tendon equivalent in ninhydrin color to 1.0 μmole of leucine in 5 hours at pH 7.4 at 37 °C in the presence of calcium ions.

| Application: | Collagenase from Clostridium histolyticum has been used to dissociate tissue samples such as spleens and testicular tissue. |
| Application: | 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. When this enzyme is tested for suitability for the release of hepatocytes. The collagenase is used at approximately 1 mg/mL in a total volume of 100 mL for each rat liver. |
| Biochem/physiol Actions: | Collagenase is activated by four gram atom calcium per mole enzyme. It is inhibited by ethylene glycol-bis(beta-aminoethy |
| Biochem/physiol Actions: | Effective release of cells from tissue requires the action of both collagenase enzymes and the neutral protease. Collagenase is activated by four gram atom calcium (Ca2+) per mole enzyme. The culture filtrate is thought to contain at least 7 different proteases ranging in molecular weight from 68-130 kDa (pH optimum: 6.3-8.8). The enzyme is typically used to digest the connective components in tissue samples to liberate individual cells. Collagenase treatment can cause some cells to die. Typically, concentrations varying from 0.1 to 5 mg/mL is used for digestion. The duration of reaction varies from 15 minutes to several hours, which enables efficient cell dissociation without causing too much cell death. Krebs Ringer buffer with calcium and BSA is preffered and Zn2+ is required for its activity. |
| Disclaimer: | As supplied, this product is stable for one year at -20°C. There is no loss in FALGPA or protease activity in 30 days at 37°C, 50°C and -20°C. Solutions of crude collagenase are stable if frozen quickly in aliquots (at 10 mg/mL) and kept frozen at -20°C. Further freeze-thaw cycles will damage the solution. The product retains 100% activity over 7 hours when held on ice. |
| General description: | Clostridium histolyticum consists of two classes of collagenases, which cleaves at multiple cleavage sites within the collagen triple helix. It is more effective than mammalian collagenases. Clostridial collagenase is implicated |
| Other Notes: | One collagen digestion unit (CDU) liberates peptides from collagen from bovine achilles tendon equivalent in ninhydrin color to 1.0 μmole of leucine in 5 hours at pH 7.4 at 37 °C in the presence of calcium ions. One FALGPA hydrolysis unit hydrolyzes 1.0 μmole of furylacryloyl-Leu-Gly-Pro |
| Preparation Note: | Prepared from Type IV (C5138). A stock solution may be prepared by dissolving 0.05-0.1 mg/mL of collagenase in 50 mM TES buffer containing 0.36 mM calcium chloride (TESCA) (pH 7.4) at 37 °C. This product also contains clostripain, nonspecific neutral protease, and tryptic activities. |
