CD CHO AGT™ (Advanced Granulation Technology) medium is a protein-free, chemically-defined medium optimized for the growth of Chinese hamster ovary (CHO) cells and expression of recombinant proteins in suspension culture. The AGT™ dry media format is designed to provide increased consistency and productivity across all stages of production from development to commercial manufacturing. CD CHO AGT™ 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-)

Liquid Media Formulations
Gibco® AGT™ media are also available in a liquid format that offers the same performance and formulation as the AGT™ media format. Gibco® liquid media are manufactured animal origin-free with the same complete, serum-free, protein-free, chemically-defined formulation and performance as their AGT™ media counterparts.
