Abstract
Methods of protein production in a linked culture and production bioreactor system are provided. Such methods include a culture bioreactor (N−1 bioreactor) linked to production bioreactor (N bioreactor). More specifically, the methods include (a) culturing cells with a gene that encodes the protein of interest in a continuous perfusion culture bioreactor (N−1 bioreactor); inoculating a continuously stirred tank reactor (CSTR) production bioreactor (N bioreactor) with cells obtained from step (a); and culturing the cells in the CSTR production bioreactor under conditions that allow production of the protein of interest.
