CD CHO medium is a protein-free, serum-free, chemically-defined medium optimized for the growth of Chinese hamster ovary (CHO) cells and expression of recombinant proteins in suspension culture. With a proven track record of quality for more than 10 years, CD CHO medium contains no proteins or peptide components of animal, plant, or synthetic origin, as well as no undefined lysates or hydrolysates.

When to Use CD CHO Medium
• Your GS CHO cells are recommended to be grown in CD CHO medium
• Your cells have been successfully cultured in CD CHO medium in the past and your process is nearing a regulatory filing (DMF available)

When to Consider Another Gibco™ Medium

Consider CD FortiCHO™ medium when:
• The cell line you are using is a transfected CHO K1, GS CHO or CHO-S™ cell line
• Maximum batch culture cell densities and protein titers are needed
• You have time to adapt cells into a new medium in an effort to maximize titers
• Cell health at harvest is a priority for downstream processing

Consider CD OptiCHO™ medium when:
• You are using a transfected CHO cell line other than CHO K1, GS CHO or CHO-S™ cell lines
• Optimization of feeding strategies will be part of your base medium selection testing in an effort to maximize productivity
• Your CHO cell line is “finicky,” i.e. hard to grow or adapt

Consider CD DG44 medium when:
• You use parental DG44 or DXB11 CHO cells (dhfr-)

Dry Media Formulations
Gibco™ liquid media are available in an AGT™ (Advanced Granulation Technology) dry media format that is designed to provide increased consistency and productivity across all stages of production from development to commercial manufacturing. AGT™ media are manufactured animal origin-free with the same complete, serum-free, protein-free, chemically-defined formulation and performance as their liquid media counterparts.
