Disclosed are compounds and methods for manipulating proteins in general and membrane proteins in particular. The compounds can be prepared from cholic acid, deoxycholic acid, lithocholic acid, or derivatives thereof. The compounds typically possess critical micelle concentrations lower than those of known detergents such as CHAPS and CHAPSO. Accordingly, lower amounts of the compounds are required for effective solubilization of membrane proteins. The compounds can be used aid the solubilization, isolation, purification, stabilization, crystallization, and/or structural determination of membrane proteins.
本文披露了一种通用蛋白质和特定膜蛋白的操作化合物和方法。这些化合物可以由胆酸、去氧胆酸、石胆酸或其衍生物制备而成。这些化合物通常具有临界胶束浓度低于已知的去垢剂(如CHAPS和CHAPSO)的化合物。因此,相对较少的这些化合物就能够有效溶解膜蛋白。这些化合物可用于辅助膜蛋白的溶解、分离、纯化、稳定、结晶和/或结构测定。
