描述

别名 3-[(3-胆固醇氨丙基)二甲基氨基]-1-丙磺酸 ;3-[3-(胆酰胺丙基)二甲氨基]丙磺酸内盐;3-[(3-Cholamidopropyl)dimethylammonio]propanesulfonate; 3-[(3-Cholamidopropyl)dimethylammonio]-1-propanesulfonate; CHAPS
产品介绍 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。CHA?PS 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。CHAP?S 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。
用途 两性表面活性剂,CHAPS 是一种非变性的zwitterionic 去垢剂、蛋白质裂解液,用于溶解膜蛋白和裂解蛋白和蛋白之间的相互作用。
生化机理 CHAPS is a zwitterionic nondenaturing detergent for solubilizing membrane proteins. CHAPS is often used as a detergent in the solubilization and purification of membrane proteins for several advantageous reasons. CHAPS detergent is non-denaturing to membrane proteins, can solubilize proteins, disaggregate protein-protein interactions and is electrically neutral. CHAPS is also useful in ion exchange chromatography and isoelectric focusing as it is zwitterionic and does not exhibit a net charge between pH 2 to 12. The critical micelle concentration of CHAPS is 6-10mM.
