摘要:
The current invention reports a CHO-K1 cell, characterized in that said CHO-K 1 cell is derived from CHO-K1 cell deposited as ATCC CCL-61, grows in suspension, requires no glutamine, no insulin, and no growth factors in the cultivation medium for growth, whereby said CHO-K1 cell is not modified compared to the deposited CHO-K1 cell ATCC CCL-61 cell line by the introduction, deletion, or inactivation of a nucleic acid. Also reported are a method for obtaining said CHO-K1 cell and a method for the production of a heterologous polypeptide using such a CHO-K1 cell according to the invention.

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.
