ABSTRACT:
The invention provides processes for culturing cells derived from embryonic retinoblast cells immortalized by adenovirus E1 sequences, preferably PER.C6® (human embryonic retina) 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.
