VectorCHO Feed is a chemically defined feed medium formulated for 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 77 g/L D-glucose.

Recommended cell subtypes: CHO-DXB11, CHO DG44.

Recommended companion media: AltairCHO™, VegaCHO™ and CDFS36™ 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.
