CHO-S [suspension]

A clonal isolate, derived from Chinese hamster ovary (CHO K1) cells. The CHO-S parental cell line was selected for growth and transfection efficiency. CHO-S cells are adapted to serum-free suspension culture.

Cell Type:
Ovary Epith.
Tissue Origin:
ovarian
Species:
hamster
Research Area:
Cancer Research/Cell Biology
Cell Characteristics:
Suspension

Recommended Media

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 Medium – For concurrent transition of adherent CHO cells to serum-free and suspension culture; supports faster doubling times
- ProCHO™ 5 Medium – For CHO cells already growing in suspension; supports increased protein production

Storage = 2°C to 8°C

BE15-766 - ProCHO™ 5 powder without phenol red

PowerCHO™ Chemically Defined, Serum-free and hydrolysate-free CHO Media are non-animal origin media designed to support the growth of CHO cell lines, particularly high-density suspension cultures.

For therapeutic bioprocessing applications, these protein-free formulations also facilitate both downstream purification and regulatory compliance.

Storage = 2°C to 8°C
