FectoCHO® Expression System

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 the competitor's systems.

 : Since 2002, Polyplus-transfection® is ISO 9001 certified and since then this certification has been successfully renewed every three years.

 : FectoPRO® transfection reagent, FectoPRO® Booster and FectoCHO^® CD Expression Medium can be purchased separately.
