    摘要: A method for selecting a membrane protein with increased stability, the method comprising: a) providing one or more mutants of a parent membrane protein in a membrane-containing composition, wherein the one or more mutants are exposed to an amount of a membrane destabilizing agent which is effective to destabilize the parent membrane protein in-situ, b) determining whether the or each mutant membrane protein has increased stability with respect to its structure and/or a biological activity compared to the stability of the parent membrane protein with respect to its structure and/or the same biological activity, and c) selecting the one or more mutants which have increased stability compared to the stability of the parent membrane protein.
