Cultures of E1-immortalized cells and processes for culturing the same to increase product yields therefrom

摘要

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.
