| Zusammenfassung: | The present inventions provide methods to control the heterogeneity of Fc-containing proteins, such as antibodies produced in cell culture, particularly mammalian cell culture by controlling culture pCO2, as well as products produced by these methods. Among other things, the inventions provide for lowering the percentage of acidic charge variants in antibody products. Proteins that comprise Fc moieties include but are not limited to Fc-containing proteins, such as antibodies and antibody derivatives, and fragments of both. |
