First CHOice® Medium is a cultivation and production medium optimized for CHO platform technology. The completely chemically defined and protein free medium has been developed in close cooperation with customers using CHO-S, DG44 and CHO-K1 cell lines to boost cell growth and to increase protein expression and quality. The medium enhances performance by minimising the production of stress related metabolites such as lactate and ammonia and thereby conserves high viabilities in all process phases.
We request our clients to test this medium for any projects in which titer needs to be increased together with maintaining consistent product quality attributes.
Please kindly see the attached exemplary data for an IgG2,4 and an IgG1 antibody.
