    摘要: A method for the recombinant production of a heterologous polypeptide in a eukaryotic host cell is described. The host cell comprises an expression plasmid, whereby the expression plasmid comprises in a 5′ to 3′ direction a) a promoter, b) a nucleic acid encoding a first polypeptide, whose amino acid sequence is selected from Table 1 depending on the first two amino acids of the second polypeptide, c) a nucleic acid encoding a second polypeptide comprising a nucleic acid encoding a heterologous polypeptide, a nucleic acid encoding a linker, and a nucleic acid encoding an immunoglobulin fragment, and d) a 3′ untranslated region comprising a polyadenylation signal. Further a plasmid and a kit are described.

    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.
