Outline of Final Research Achievements |
To investigate the mechanism of antibody aggregation during cultivation, the aggregation was analyzed during cultivation. The aggregation was observed in CHO cell. We have developed the CHO cell culture methods to suppress antibody aggregation by trehalose addition. Despite reducing aggregation, the cultivation method causes the inhibition of cell growth due to the increased osmotic pressure by trehalose addition. By introduction of the trehalose transporter we can attain both suppressed antibody aggregation and improved cell growth.
