Descrizione generale
Collagenase is a protease which cleaves the triple-helical protein called collagen. There are three types of tissue collagenases, and these belong to the matrix metalloproteinases (MMP) family. Collagenase obtained from Clostridium histolyticum has a very strong activity, as it digests collagen from both ends, at temperatures as low as 4-10°C. Crude collagenase mixtures contain two major enzyme types namely, collagenase and clostripain.
Applicazioni
Collagenase from Clostridium histolyticum is used for the following applications:
This product is suitable for the disaggregation of human tumor, mouse kidney, human adult and fetal brain, lung and many other epithelia tissues. It has also been shown to be effective in liver and kidney perfusion studies, digestion of pancreas and hepatocyte preparation. Collagenase has also been used in the preparation of arterial tissue for the study of Advanced Glycosylation End Products. This enzyme has been tested for the release of heptatocytes at a concentration of approximately 1mg/mL. Concentrations for digestion range from 0.1 to 5mg/mL.
- Sertoli cell isolation
- Used in the comparison of enzymatic methods
- Tissue preparations for immunocytochemistry
- Testicular sperm extraction
- Preparation of single cell suspensions
- Immunofluorescence

Azioni biochim/fisiol
La collagenasi è attivata da quattro grammi atomo di calcio per mole di enzima. È inibita da etilen-glicol-bis(beta-amminoetil etere) - acido N, N, N′,N′-tetraacetico, beta-mercaptoetanolo, glutatione, acido tioglicolico e 8-idrossichinolina.
The collagenase product is a mixture of enzymes secreted by C. histolyticum, with different products differentiated by the relative ratios of the 10-18 components found in the secreted enzymes. The main components are two collagenases, clostripain, and a neutral protease. The synergistic action of these enzymes degrade collagen and other intracellular materialThe action of both collagenase enzymes and the neutral protease is necessary for effective release of cells from tissue. Various types of collagen are the natural substrates for collagenase.
Avvertenza
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.
Definizione di unità
