CD OptiCHO™ medium is specifically designed to offer high performance and yield with recombinant CHO cells in a chemically defined fed-batch environment. The protein-free, animal origin free formulation is designed to provide consistency and reduces the need to screen for adventitious agents. CD OptiCHO™ medium builds on Gibco™ CD CHO’s legacy of consistent cell growth and titers, while offering up to 40% better titer and cell growth over select competitors. Thanks to its low osmolality and advanced CHO CD EfficientFeed™ Liquid Nutrient Supplement Kit feeding options, CD OptiCHO™ medium is capable of gaining 2-5 fold increases in fed-batch productivity over batch culture.

When to Use CD OptiCHO™ Medium
• 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

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 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 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.
