Amazing protein yields
FectoPRO® enables amazingly high protein and antibody yields in both CHO and HEK-293 cells grown in suspension in serum-free media (Fig 1).
FectoPRO® largely outperforms other transfection reagents such as linear PEI commonly used in Bioproduction processes in terms of transfection efficiency (Fig. 2), leading to superior protein production yields (Fig. 3).
Cost-effective: uses low plasmid DNA amounts
High quality plasmid DNA preparation can be very costly, especially when large DNA amounts and many plasmids are required for large-scale protein production. FectoPRO® saves 40 to 60% on DNA cost by using 0.4 to 0.6 µg DNA / 106 cells / ml of cell culture; hence making this kit an affordable and economical solution for Bioproduction processes.
Sustained protein production
The duration of protein production processes has increased in the past few years, and most of the protein production processes now last 1-2 weeks to obtain optimal amount of produced protein. FectoPRO® has been developed to ensure sustained protein production over several days, while maintaining high cell viability for longer lasting protein production (Fig. 4.).
Easily scalable
Streamline your bioproduction process with a robust protocol that is easily adapted to various culture vessels. FectoPRO®-mediated transfection can be scaled linearly from 30 ml up to liters of cell culture without protocol adaptation (Fig. 5.).
Reproducible production yields
FectoPRO® is manufactured and formulated using a highly controlled production process. This ensures highly reproducible results from experiment to experiment. Moreover, in order to meet current regulatory guidelines, FectoPRO® is released using advanced quality controls including a specification for protein productivity that guarantees excellent lot-to-lot consistency (Fig. 6).
Compatible with mammalian expression systems
Unlike other commercially available reagents, FectoPRO® transfection kit is suitable for both CHO and HEK-293 cells (Fig. 2 and 3). The reagent is compatible with various media formulations; hence lab implementation is easy and straightforward (Fig. 7, Table 2).

Transient protein production
Protein production consists in overexpressing a recombinant protein or peptide in a cell line at small / medium to large scale. The biomolecules produced can be used for research purposes like structural characterization all the way down to therapeutic or medical applications.
Available application Notes:
High density cell systems for protein production using FectoPRO
Recombinant protein production for therapy and diagnostic applications is mainly achieved using HEK-293 and CHO cells cultivated in suspension cultures without serum. The latter has been removed from raw materials for various reasons (costs, downstream purification steps, reproducibility…) while culture in suspension has been implemented to increase productivity. Improvements in culture processes and cell line engineering led to the generation of high-density mammalian transient protein expression systems.

“In our hands, FectoPRO® gives the highest protein production yields we ever reached using transient transfection. Our company offers custom services including protein production in mammalian cells. Being able to produce a lot more protein without revisiting our expression system opens a whole new range of possibilities for our antibody and protein production services”.
Philippe F., ProteoGenix SAS, France“I have to admit I had low expectations for FectoPRO®. Perhaps a modest improvement in transfection … an extra 5-10%. J. did her first experiment yesterday and analyzed it today and the result was remarkable. I’m shocked by both the efficiency of transfection and the brightness of the GFP.”
Thomas C., Biotech, Cambridge, MA, United States“FectoPRO® yields transient expression titers in HEK, matching or exceeding those from other suppliers, but at a fraction of the price.”
James L., Biotech company, United States“2 x the yield for half the amount of transfection reagent = 4 x less cost. It is also very easy to use.”
Jean-Philippe J., Hospital for Sick Children, Canada
