Cellvento™ CHO-100 is a non-animal origin, chemically defined medium that can provide strong cell growth, high productivity, and lot-to-lot consistency. The new media formulation was designed for the long-term growth of CHO cells to express antibodies or protein products. Cellvento CHO-100 contains no hydrolysates or components of unknown composition. It was designed to achieve high cell densities in batch mode operation.
