BalanCD Transfectory CHO system of media and supplements is a scalable platform that produces milligram to gram-scale yields of recombinant proteins using a simplified, affordable protocol. The system (including BalanCD Transfectory CHO, Transfectory Supplement and Anti-Clumping Supplement) supports small- andLarge-scale transient transfection in CHO cells, enabling scientists to use the same medium before and after transfection.The chemically-defined, animal component-free medium produces proteinLevels equivalent to, or better than, other commercially available media.
