ProCHO™ Protein-free CHO Media were developed specifically to facilitate the production and downstream processing of recombinant proteins expressed in CHO cells. These protein-free formulations support high-density cultures without the need for animal derived components. Very low levels of recombinant insulin facilitate both downstream purification and regulatory compliance. The following media systems are available:
ProCHO™-4 - For concurrent transition of adherent CHO cells to serum-free and suspension culture. Supports faster doubling times. Cat. No. 12-029Q contains phenol red and 0.1% Pluronic® F-68. Does not contain L-glutamine, hypoxanthine, or thymidine. Cat. No. 04-919Q is similar to 12-029Q except that it does not contain phenol red.
ProCHO™-5 - For CHO cells already growing in suspension. Supports increased protein production. Contains 0.1% Pluronic® F-68. Does not contain L-glutamine, phenol red, hypoxanthine, or thymidine.
ProCHO™-AT - For adherent culture of CHO cells. Contains L-glutamine. Does not contain hypoxanthine or thymidine.
