The innovative DYNAMIC.CHO Media System™ was designed for small- and large-scale protein production using Chinese Hamster Ovary (CHO) cells. These robust cells are used for the industrial production of a variety of recombinant proteins requiring complex post-translational modifications and correct protein folding. The DYNAMIC.CHO Media System™ is highly suitable for fed-batch cultures. It improves the yield and concentration of recombinant proteins through the optimization of a selection of essential nutrients and growth-promoting factors. The DYNAMIC.CHO Media System™ was specially designed in close cooperation with our biopharmaceutical cooperation partner using CHO-S, CHO-DG44, and CHO-K1 cell lines.
