規格：100mg 1g

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.
Quality
也具有梭菌蛋白酶、非特異性中性蛋白酶和胰蛋白酶活性。
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 may be used for the isolation of cells from many types of animal tissue. VETEC Collagenase Type I has the original balance of collagenase, caseinase, clostripain, and tryptic activities, and is suggested for epithelial, liver, lung and adrenal primary cell isolations.
