摘要:
Provided herein are methods of processing a cell culture and open circuit filtration systems. The filtration systems comprise a tangential flow filtration (TFF) unit having independent inlet and outlet ports connecte to the cell culture bioreactor and a pump adapted to the reverse the flow of fluid through the filtration unit.
摘要:
Disclosed herein are methods that have been developed to control the formation of disulfide bonds between polypeptides of a multimeric protein produced by a bioprocess. Also disclosed are protein solution parameters that allow for controlling the formation of disulfide bonds. In one example, the methods disclosed herein can be used to control the proportion of half antibody molecules in an antibody solution.
