Abstract
Chinese hamster ovary (CHO) and human embryonic kidney 293 (HEK293) cells are the two most important mammalian hosts for the production of recombinant proteins. In this chapter, the suspension cultivation and transfection of these cells in small-scale, single-use orbitally shaken bioreactors, TubeSpin™ bioreactor 50 [orbitally shaken reactor 50 (OSR50)], and TubeSpin™ bioreactor 600 [orbitally shaken reactor 600 (OSR600)] are described. These are conical centrifuge tubes with nominal volumes of 50 mL and 600 mL, respectively, that have been redesigned with a ventilated cap for the cultivation of animal cells in suspension at working volumes up to 20 mL and 400 mL, respectively.
