Bringing membrane proteins into aqueous solution generally requires the use of detergents or other amphiphilic agents. The invention provides a new class of amphiphiles, each of which includes a multi-fused ring system as a lipophilic group. These new amphiphiles confer enhanced stability to a range of membrane proteins in solution relative to conventional detergents, leading to improved structural and functional stability of membrane proteins, including integral membrane proteins. Accordingly, the invention provides new amphiphiles for biochemical manipulations and characterization of membrane proteins. These amphiphiles display favorable behavior with membrane proteins and can be used to aid the solubilization, isolation, purification, stabilization, crystallization, and/or structural determination of membrane proteins.
将膜蛋白引入
水溶液通常需要使用洗涤剂或其他两性分子试剂。该发明提供了一类新型两性分子,每种都包括一个多融合环系统作为亲脂基团。这些新型两性分子相对于传统洗涤剂在溶液中赋予了一系列膜蛋白增强的稳定性,从而提高了膜蛋白的结构和功能稳定性,包括整合膜蛋白。因此,该发明提供了用于生化操作和膜蛋白表征的新型两性分子。这些两性分子与膜蛋白表现出良好的行为,并可用于辅助膜蛋白的溶解、分离、纯化、稳定化、结晶和/或结构测定。
