Figure 1From: Serum-free microcarrier based production of replication deficient Influenza vaccine candidate virus lacking NS1 using Vero cellsVero cell microcarrier cultivation in different commercial serum-free media. (A) Comparison of Vero cell growth on Cytodex 1 microcarriers in five different serum-free media, OptiPro SFM, EX-CELL Vero SFM, VP-SFM, Provero-1 and HyQ SFM4MegaVir. The experiment was performed in duplicate using 250 ml spinner flasks with 3 g/l Cytodex 1 microcarriers. The viable cell concentrations of one representative run are shown here. (B) Phase contrast images of cells cultured on Cytodex 1 microcarriers in EX-CELL Vero SFM and OptiPro SFM at day 8. Scale bars indicate 200 μm.Back to article page
