Application
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, isolation of nonparenchymal rat liver cells 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 1 mg/mL. Concentrations for digestion range from 0.1 to 5 mg/mL.
Use for the digestion of collagen and the release of adherent cells from substrates.
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.
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 material. The 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.
Caution
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.
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.
Preparation Note
This collagenase is obtained from the culture filtrate of type VII (C0773) Clostridium histolyticum. The culture filtrate is thought to contain at least 7 different proteases ranging in molecular weight from 68-130 kDa. Solutions are typically prepared at 1-2 mg/mL in TESCA buffer (containing 50 mM TES, 0.36 mM Calcium chloride, pH 7.4 at 37°C.

In this study, to investigate the effect of overexpression of miR-146a on autophagy of hippocampal neurons in rats with intracerebral hemorrhage (ICH), 72 Sprague-Dawley rats were randomly divided into the sham, ICH, miR-146a agomir, and miR-146a agomir control groups. The
ADAMTS1 protease is required for a balanced immune cell repertoire and tumour inflammatory response.

Recent advances have emphasized the relevance of studying the extracellular microenvironment given its main contribution to tissue homeostasis and disease. Within this complex scenario, we have studied the extracellular protease ADAMTS1 (a disintegrin and metalloprotease with thrombospondin motif 1), implicated

Active site metal substitutions for both gamma- and zeta-collagenases from Clostridium histolyticum have been made by direct metal exchange. The incubation of Co(II), Cu(II), Ni(II), Cd(II), and Hg(II) with these native collagenases results in changes in activity that parallel those

Both gamma- and zeta-collagenases from Clostridium histolyticum are fully and reversibly inhibited by 1,10-phenanthroline at pH 7.5 in the presence of 10 mM CaCl2 with KI values of 0.11 and 0.040 mM, respectively. The inhibition is caused by removal of
Articles
Hepatocytes are epithelial cells found in the liver. They perform important functions, such as helping to detoxify blood, and to synthesize transport proteins, such as lipoprotein, albumin and transferrin. Primary and secondary cultures of hepatocytes are useful for studying the mechanisms of liver regeneration and differentiation.
