Methods and perfusion culture systems are disclosed. The systems and methods relate to decreasing the starting perfusion rate, resulting in increased residence time of the cells in the bioreactor and the cell retention device, and/or concomitantly increasing the starting bioreactor volume or decreasing the starting cell retention device volume, or both. Other method embodiments include increasing the concentrations of individual components of the tissue culture fluid, and adding a stabilizer of the degradation of the recombinant protein. |
