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.
