Bioreactor scale-up methods
WebControl of carbon dioxide within the optimum range is important in mammalian bioprocesses at the manufacturing scale in order to ensure robust cell growth, high protein yields, and consistent quality attributes. The majority of bioprocess development work is done in laboratory bioreactors, in which carbon dioxide levels are more easily controlled. WebMoving from research and development to production requires reliable and robust methods for scaling-up antibody production processes. However, small-scale processes do not always scale up seamlessly into larger volumes. ...
