High density cell culture
WebWe observed how these parameters impacted viable cell density, viability, and final IgG production of different CHO cell lines when exposed to cell culture medium containing DMSO (Figure 1). The CHO-S clone used in this study showed the highest sensitivity and deviation compared to other clones (CHO-K1, CHO-DG44, CHOZN ® ; data not shown). WebIn high cell density cryopreservation, or HCDC, cells banked at high density (ex: 50-100 x 10 6 VC/mL) and high volume (150 mL) can intensify the seed train expansion process. HCDC removes the need for traditional seed train expansion and begins with frozen seed train intermediates in a single-use bag. These cells then undergo one seed train ...
