Methods for producing soluble membrane-spanning proteins

摘要

Methods for producing membrane-spanning polypeptides in high yields, with native conformation, and/or in soluble form include solubilizing in non-ionic or zwitterionic detergents, as well as use of promoters and expression vectors for expressing high yields of membrane-spanning polypeptides in bacterial cells. Mutated promoters provide tight control of membrane-spanning polypeptides in bacterial cell hosts.
