    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 CO2 (pCO2) 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 CO2 (pCO2) in the medium during the production phase of the eukaryotic cells to a second value.
