Method for recombinant production of polypeptides

摘要

A method for the recombinant production of a polypeptide by expressing a nucleic acid encoding said polypeptide in a microbial host cell, forming in the cytoplasm of said host cell inclusion bodies containing said polypeptide, and isolating, solubilizing and naturing said polypeptide, characterized in that after fermentation the host cell or the host cell content is incubated at a temperature of 40° C. or higher for at least 10 minutes and subsequently insoluble polypeptide is isolated from the host cell, this method providing an improved yield in inclusion bodies containing the desired polypeptide.
