一般描述

CHAPSO 是非变性两性离子胆盐衍生物。 通过添加功能性羟基衍生自 Chaps。

应用

CHAPSO用于：
  • 在一项研究中，评估两种转运蛋白脂质体的溶解和重建过程
  • 在一项研究中，研究新型bicelle体系在宽温度范围内对大分子进行定向
  • 与二月桂酰基磷脂酰胆碱（DLPC）混合，用固态核磁共振（NMR）技术中研究膜相关蛋白
具有类似于 CHAPS 特性的非变性两性离子洗涤剂，然而由于具有更强极性的头部基团而更易溶解。适用于内在膜蛋白的增溶。

We have prepared and characterized a novel bicelle system composed of 1,2-di-O-dodecyl-sn-glycero-3-phosphocholine (DIODPC) and 3-(chloramidopropyl)dimethylammonio-2-hydroxyl-1-propane sulfonate (CHAPSO). At the optimal DIODPC/CHAPSO molar ratio of 4.3:1, this medium becomes magnetically oriented from pH 6.5 down to pH 1.0. Unlike previously reported

The process of liposome solubilization and reconstitution of two transport proteins have been studied using Chaps and Chapso (3-[(3-cholamidopropyl)dimethylammonio]-2- hydroxy-1-propanesulfonate). The solubilization of unilamellar liposomes was followed by absorption experiments and the process was shown to fit well to the

Over 50 detergents were tested to establish which would be most effective in releasing proteins from membrane-bounded compartments without denaturing them. Various concentrations each of detergent were tested for two activities: (1) solubilization of egg phospholipid liposomes as measured by
