With CD FortiCHO medium cell cultures last 2+ days longer than competitive alternatives, which means decreased HCP (Host Cell Protein) concentration for removal in downstream purification.

CD FortiCHO medium is fortified to support maximal recombinant CHO cell growth and protein expression in suspension batch culture, offering 120% greater growth and production than select competitive media with simple glucose supplementation. CD FortiCHO medium can provide up to 75% greater fed-batch growth and production over glucose-only fed-batch culture for selected cell lines and applications when used with CD EfficientFeed C nutrient supplement.

When to Use CD FortiCHO Medium:
 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

When to Consider Another Gibco Medium:

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 CHO medium when:
 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)

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

Dry Media Formulations:
Dynamis AGT Medium is the comparable dry format for scale up.
