ABSTRACT:
Provided are processes for culturing cells derived from embryonic retinoblast cells immortalized by adenovirus E1 sequences, such as PER.C6® cells, to improve product yields from such cells. Feed strategies for such cells and cultures with very high cell densities are provided, resulting in high yields of products, such as recombinant antibodies.
