EX-CELL^® CD CHO Fusion

EX-CELL^® CD CHO Fusion is a chemically defined, animal-component free medium developed for the long-term growth of Chinese Hamster Ovary (CHO) cells. The absence of any large macro molecules allows for isolation and purification of secreted proteins from the cells. This medium is supplied without L-glutamine to aid in media stability, to avoid L-glutamine degradation that causes ammonia build-up and to provide an appropriate medium for the culture of CHO cells using glutamine synthetase selection (example: MilliporeSigma’s CHOZN GS knockout cell line). This medium does not contain hypoxanthine or thymidine to allow for its use with dihydrofolate reductase(DHFR-) gene amplification systems (example: MilliporeSigma’s CHOZN DHFR knockout cell line).

Formulated to contain 20.9 grams of powder per liter of medium.
