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 macromolecules 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 the Glutamine Synthetase, or GS System™. This medium does not contain hypoxanthine or thymidine to allow for its use with dihydrofolate reductase (DHFR) gene amplification systems.

Chinese hamster (Cricetulus griseus) ovary-derived Chinese hamster ovary (CHO) cells are the most commonly used mammalian hosts for the industrial production of recombinant therapeutics because of their ability to fold, assemble, and perform post-translational modifications, such as glycosylation, on proteins.
