For the first time, achieve superior protein yields using transient transfection and gene expression. FectoPRO® Transfection reagent is specifically designed for enhanced Transient Gene Expression (TGE) in suspension CHO and HEK-293 cells in various serum-free media, using low DNA amount (< 1 µg/ml of cell culture). FectoPRO®-mediated transfection process is easily scalable from a few ml to several liters of cell culture, ensuring robust reproducible protein production. Increased productivity and low DNA amount requirement make FectoPRO® a cost-effective solution for bioproduction processes.
