A chemically defined medium Hybris-1-CHO designed for suspension culturing and recombinant protein production by CHO cell lines has been characterized. The two-stage character of cell growth and basic biochemical parameters was demonstrated in both batch and fed-batch experiments with the CHO-S model cell line. The data on the culture growth rate, its morphology, concentrations of key metabolites, and also culturing characteristics of the medium and darbepoetin productivity of the cultures on Hybris-1-CHO in comparison with a few commercial media permit to regard the designed medium as applicable to maintaining of protein biotechnological production.

 

Key words:  CHO-S;  darbepoetin;  recombinant protein;  serum-free medium;  suspension culturing.
