Enhancement Of Transient Transfection With Serum-Free And Blood-Free Transferrin
Methods to enhance transient transfection of adherent cells have identified many different ligands that improve plasmid uptake into cells. Of these ligands, serum-derived transferrin is well-known to improve transfection efficiency of adherent cells. However, to date, a serum-free and blood-free transferrin has not been tested for improvements to transfection efficiency. We have thus created a protocol for the improvement of transfection efficiency and viral titer without the need for blood-derived transferrin. Excess transferrin does not negatively impact transfection, and the incorporation of a blood- and serum-free, recombinant human transferrin supports high transfection efficiency and viral titer in a chemically defined, blood-free medium.
