From: Protection of bioreactor culture from virus contamination by use of a virus barrier filter
(a) NMR fingerprinting of media pre-filtration (dark blue) or post Viresolve®Barrier filtration (light blue) showed no change in media composition. (b): Cell growth of fed-batch cultures using Viresolve®Barrier filtered media and feeds (VB+) or 0.22µM filtered media and feeds (VB-). (c): Product quality of the mAb is unchanged by virus filtration of the media and feeds. All attributes displayed as a ratio of VB+/VB-.
