StarCHO Medium | OPM Biosciences

StarCHO is a chemically defined basal medium formulated for thawing, passaging, and supporting high-density fed-batch processes across multiple Chinese hamster ovary (CHO) cell subtypes. It is hydrolysate-free, animal-origin free (AOF), and does not contain L-glutamine. It contains 6 g/L D-glucose.

Recommended cell subtypes: CHOZN GS-/-.

Recommended companion media: StarCHO™ Feed Plus and CDFS12™ Feed Supplement.

This product is intended for research use or further manufacturing, including large-scale biopharmaceutical production. It is not intended for direct human administration or use as a drug substance or drug product.

StarCHO Medium, when fed StarCHO Feed and CDFS36 Feed Supplement, outperformed a competitor in CHOZN GS-/- mAb expression, showing 130% titer increase on day 14, with higher late-stage VCDs and comparable viability.
