木瓜蛋白酶产品信息

 

来源: Carica Papaya Latex

IUB:3.4.22.2

木瓜蛋白酶是来自Carica papaya乳胶的巯基蛋白酶。它的分子量为23kDa,适pH范围为6.0-7.0。木瓜蛋白酶对亮氨酸甲酯的作用产生不溶性聚亮氨酸肽。木瓜蛋白酶分解软骨的细胞间基质。木瓜蛋白酶被半胱氨酸,硫化物和亚硫酸盐活化。稳定剂是EDTA,半胱氨酸和二巯基乙醇。

稳定性/储存: 在2-8°C下稳定6-12个月。不要冷冻水悬浮液。

技术注释:木瓜蛋白酶制剂应在使用前在活化溶液中培养,以确保*活动。应用包括抗体片段化和原代/神经细胞分离。

单位定义:在含有1.1mM EDTA,0.067mM巯基乙醇和5.5mM半胱氨酸-HCl的溶液中活化30分钟后,一个单元在25℃,pH6.2下每分钟水解一微摩尔苯甲酰-L-精氨酸乙酯。

Papain, Suspension
Supplied as a two times crystalline suspension in 50mM sodium acetate, pH 4.5. To ensure full activity, the enzyme should be incubated in a solution containing 1.1mM EDTA, 0.067mM mercaptoethanol and 5.5mM cysteine-HCl for 30 minutes. It is recommended that the enzyme be 0.22 micron filtered after dissolution and prior to use. 
Store at 2-8°C. 
REQUIRES SPECIAL SHIPPING: ICE PACK

PDS Kit, Papain Vial
A component of the Papain Dissociation System, for use in the tissue dissociation method of Huettner, J.E., and Baughman, R.W.: J. Neuroscience, 6, 3044 (1986). Contains papain, L-cysteine, and EDTA. This material is 0.22 micron membrane filtered and lyophilized in autoclaved vials. A vial reconstituted with 5 ml of EBSS or equivalent yields a solution at 20 units of papain per ml in 1mM L-cysteine with 0.5mM EDTA. 
Store at 2-8°C.
