一般描述

CHAPS是一种非变性两性离子磺基甜菜碱洗涤剂,性温,可溶解膜蛋白和受体。它有助于打破蛋白质间的相互作用,是天然胆汁盐的衍生物。它具有小胶束分子量(6,150)和高临界胶束浓度(6 - 10 mM),允许通过透析将其从样本中除去。

应用

  • 10mM CHAPS洗涤剂已用于离子交换色谱过程,旨在改善纯化。
  • 0.5w/v CHPS是蛋白质纯化中高盐缓冲液的一种成分,与HEPES、NaCl和EDTA一起使用。
  • HEPES缓冲液已被用作免疫沉淀反应中的裂解缓冲液,补充了1% CHAP。

Tetraspanins are cell membrane-scaffolding proteins interacting with one another and a repertoire of interaction partners. Through these interactions, they form extended molecular networks as tetraspanin webs or tetraspanin-enriched microdomains. Microscopic data suggest that these networks contain tetraspanin clusters, with poor
