FectoCHO® expression system consists in the synergistic association of a novel CHO chemically defined medium, FectoCHO® CD expression medium and a powerful transfection reagent, FectoPRO®.

• Outstanding protein production yields in various CHO cells
• Fast and effortless CHO cell adaptation
• Chemically defined kit components
• Excellent lot to lot reproducibility
• Cost-effective solution

FectoCHO® CD expression medium allows easy cultivation of various strains of CHO cells such as CHO-K1, CHO-S and ExpiCHO®-S , without the need of an extensive sequential adaptation. FectoPRO®-mediated transient transfection in this chemically defined medium leads to the highest protein and antibody yields ever reached using Transient Gene Expression, up to 4 times higher than with similar systems.
