DETAILS

Description (English)

Application
CHAPS is a nondenaturing zwitterionic detergent for membrane biochemistry.Useful for solubilizing membrane proteins and breaking protein-protein interactions. CHAPS’ small micellar molecular weight (6,150) and high critical micelle concentration (6-10 mM) allow it to be removed from samples by dialysis. It is also suitable for protein solubilization for isoelectric focusing and two-dimensional electrophoresis. CHAPS is commonly used for non-denaturing (without urea) IEF and has been shown to give excellent resolution of some subcellular preparations and plant proteins. Concentrations between 2-4% (w/v) are typically used in an IEF gel.
Other Notes
Zwitterionic detergent for the solubilisation of membrane proteins. Combines the useful properties of both the sulfobetaine-type and the bile salt detergents1,2; As a non-toxic stabilizing agent for growth factors3

Description (简体中文)

Application
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。
