MDCK cell growth and H9N2 virus production in stirred tank bioreactors (n = 3) and shake flasks (n = 3). a Viable cell concentration (black circle) and cell viability (black triangle) of MDCK cells in bioreactors (black) and shake flasks (gray). b HA titers of viruses produced by MDCK cells in bioreactors (black) and shake flasks (gray). The inset in the panel is a TEM picture of purified viruses harvested from one of the bioreactors. c The calculated cell-specific virus yield of the viruses in bioreactors (black column) and shake flasks (gray column)
