A method for controlling the main complex N-glycan structures and the acidic variants and variability in bioprocesses producing recombinant proteins |
摘要 |
The present invention relates to a method of controlling quality and quantity of posttranslational modification of a recombinantly produced polypeptide/protein (glycoprotein), wherein the posttranslational modification affects the glycosylation profile and/or the acidic variants profile, as manifested in CEX profiles, wherein the polypeptide/protein (glycoprotein) production is in eukaryotic host cells, the method comprising the following steps:
a) cultivating the eukaryotic cells in a suitable medium under conditions which allow the expression of the polypeptide/protein, wherein the content of the dissolved CO 2 (pCO 2 ) in the medium is at a first value during the initial growth phase of the eukaryotic cells, allowing the eukaryotic cells to grow, and
b) increasing or decreasing the content of the dissolved CO 2 (pCO 2 ) in the medium during the production phase of the eukaryotic cells to a second value. |
