用于消化组织中连接部分使其成为单个细胞，用于哺乳动物组织细胞解离胶原蛋白酶 来源于溶组织梭菌Collagenase from Clostridium histolyticumpurified by chromatography, Type III, 2-10 FALGPA units/mg solid, ≥250 CDU/mg solid (CDU = collagen digestion units), lyophilized powderBiochem/physiol ActionsCollagenase 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.Crude collagenases are mixtures of enzymes (mostly proteases) secreted by C. histolyticum. 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.包装Product sold on the basis of collagen digestion units (CDU).Preparation NoteCollagenase may be dissolved in TESCA buffer (50 mM TES, 0.36 mM Calcium chloride, pH 7.4 at 37 °C) at 0.05-0.1 mg/mL concentration.Unit DefinitionOne 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.ApplicationCollagenase from Clostridium histolyticum may be used for the isolation of cells from many types of animal tissue. It may be used for the disaggregation of human tumor, mouse kidney, human adult/fetal brain, lung and many other tissues. It may also be used in liver and kidney perfusion studies, for the digestion of pancreas, isolation of nonparenchymal rat liver cells and for hepatocyte preparation.type Type IIIform lyophilized powderpurified by chromatographysolubility TESCA buffer (50 mM TES, 0.36 mM Calcium chloride, pH 7.4): soluble0.05-0.1 mg/mL at 37 °Cforeign activity Clostripain, may contain trace amount neutral protease <1 unit/mg solidstorage temp. −20°C备注：产品信息可能会有优化升级。请以实际标签信息为准。备注：以上数据均来自公开文献, Solarbio暂未进行独立验证, 仅供参考。These protocols are for reference only.
