產品介紹

膠原蛋白酶 來源于溶組織梭菌 膠原蛋白酶 來源于溶組織梭菌 

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 II has higher clostripain activity, and is suggested for bone, heart, liver, thyroid and salivary primary cell isolations.
