一般描述
Zwitterionic detergent that combines features of bile salts and N-alkyl sulfobetaines. Better at solubilizing proteins than structurally-related carboxylic acid anions and is much more effective at breaking protein-protein interactions than either sodium cholate or TRITON™ X-100 Detergent. Capable of solubilizing the opiate receptor to a state exhibiting reversible binding of opiates. Also, capable of disaggregating cytochrome P450 to its monomeric form without denaturation. Has a small micellar molecular weight and a high critical micellar concentration and can be removed from either gels or protein solutions by dialysis across a membrane. Aggregation number: 4-14.
Non-denaturing zwitterionic detergent that combines features of bile salts and N-alkyl sulfobetaines. Better at solubilizing proteins than the structurally related carboxylic acid anions, and is more effective at breaking protein-protein interactions than either sodium cholate or TRITON™ X-100. Capable of solubilizing the opiate receptor to a state exhibiting reversible binding to opiates. Also capable of disaggregating P 450 to its monomeric form without denaturation. Has a small micellar molecular weight (6150 Daltons) and a high critical micellar concentration (6-10 mM). Can be removed from either gels or protein solutions by dialysis. Aggregation number: 4-14.
Conductivity (1.0 M, 24°C): <100 µmhos.

应用
CHAPS 是一种用于膜生物化学的非变性两性离子洗涤剂。
可用于溶解膜蛋白以及打断蛋白-蛋白相互作用。CHAPS 具有低胶束分子量 (6,150) 和高临界胶束浓度 (6-10mM)，因此可通过透析从样品中除去。它也适合在等电聚焦和二维电泳中用于溶解蛋白质。CHAPS 常用于非变性(无尿素)等电聚焦，已发现它对某些亚细胞制备物和植物蛋白能够得出优异的分辨率。通常将介于 2-4% (w/v) 间的浓度用于等电聚焦凝胶。
警告
Toxicity: Harmful (C)
重悬
Following reconstitution, store in the refrigerator (4°C). Stock solutions are stable for up to 6 months at 4°C.
