form:powder
specific activity:≥125 CDU/mg solid
storage temp.:−20°C
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.Packaging
100 mg in glass bottle1 g in glass bottle
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
Also contains clostripain, nonspecific neutral protease, and tryptic activities.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.风险提示:丁香通仅作为第三方平台,为商家信息发布提供平台空间。用户咨询产品时请注意保护个人信息及财产安全,合理判断,谨慎选购商品,商家和用户对交易行为负责。对于医疗器械类产品,请先查证核实企业经营资质和医疗器械产品注册证情况。
文献和实验丁香园网友yuanjianmei的问题为:胶原酶2一定要用D-hank's液配制吗?消化血管细胞一次要用多少啊?丁香园网友张艳红的观点为:用D-hank's液配制也可,但不一定。我做的是软骨细胞的原代培养,用的是1640完全培养基配制的。你消化血管细胞如果是做原代培养,我估计用6-8ml就可。我用时每次用8-10ml。当然,这也得视取用的组织特性和组织的量而定。仅供参考。丁香园网友wwj_5265994的观点为:不一定,我用PBS配的,我做的也是软骨细胞原代培养,用PBS配的,消化效果很好
气坏疽菌——韦氏梭菌在培养滤液中产生的一种毒蛋白。它具有蛋白酶的作用,可分解胶原蛋白和白明胶等,但不能分解卵清蛋白和血清蛋白。能对脯氨酸-X-甘氨酸 -脯氨酸 -Y这样结构的甘氨酸和脯氨酸间的结合键水解。 EC3. 4. 24. 3.
问:有人提到一种酶缓冲液提供酶反应条件,酶蛋白即催化底物明胶,不知道是怎么回事情。我要测定活性和分泌。我知道是要使用聚丙烯酰胺凝胶电泳的,请教具体的实验方法很所需要的试剂。谢谢! 答:Type IV collagenase, 72-kD, is officially designated matrix metalloproteinase-2 (MMP2). It is also known as gelatinase, 72-kD. Type IV collagenase
