Collagenase from Clostridium histolyticum

release of physiologically active rat pancreatic islets tested, Type V, ≥1 FALGPA units/mg solid, >125 CDU/mg solid

Synonym: Clostridiopeptidase A

Purchase

Description

Analysis Note

Also contains clostripain, nonspecific neutral protease, and tryptic activities.

Biochem/physiol Actions

Collagenase is activated by four gram atom calcium per mole enzyme. It is inhibited by ethylene glycol-bis(beta-aminoethyl ether) - N, N, N′,N′-tetraacetic acid, beta-mercaptoethanol, glutathione, thioglycolic acid and 8-hydroxyquinoline.

Packaging

100, 500 mg in glass bottle

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. One FALGPA hydrolysis unit hydrolyzes 1.0 μmole of furylacryloyl-Leu-Gly-Pro-Ala per min at 25°C. One Neutral Protease unit hydrolyzes casein to produce color equivalent to 1.0 μmole of tyrosine per 5 hr at pH 7.5 at 37°C. One Clostripain Unit hydrolyzes 1.0 μmole of BAEE per min at pH 7.6 at 25°C in the presence of DTT.

Application

Collagenase from Clostridium histolyticum has been used in a study to investigate the degradation of collagen by the cariogenic bacteria, Streptococcus mutans. Collagenase from Clostridium histolyticum has also been used in a study to investigate the survivability of collagen micronetworks in the presence of collagenase.

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, and lung epithelial tissues among several others. It is also effective in liver and kidney perfusion studies, digestion of pancreas, and isolation of nonparenchymal hepatocytes. The product has been used to digest forearm skin biopsies from Parkinson disease patients to grow human skin fibroblast primary cultures. The enzyme from Sigma has been used for rodent islet isolation in a study that assayed glucokinase functions.

Enzymes for Cell Detachment and Tissue Dissociation

Collagenase cleaves the peptide bonds in native, triple-helical collagen. Because of its unique ability to hydrolyze native collagen, it is widely used in isolation of cells from animal tissue. Colla...
