This application note describes the cultivation of CHO suspension cells in the Thermo Scientific™ HyPerforma™ Glass Bioreactor with a maximum working volume of 2.0 L. Using chemically defined minimal media, cell densities of up to 7.44 x 106 cells/mL were achieved. Expression of SEAP protein was induced by medium exchange and
temperature shift. Maximum SEAP activity of 63 U/mL was reached.
