I use nucleofection (Amaxa kit) method for a transfection of RFL6 cells. It' s highly efficient but I would like to try Polyethylenimine (PEI) method for RFL6 cells because it is a relatively inexpensive method.
Does anyone develop an efficient PEI transfection method for RFL6 cell line? I have used 1:10 DNA-transfection reagent ratio for nufleofection but I think this ratio could be toxic for PEI method. I haven' t used any chemical transfection method for this cell line before, do you suggest an optimal ratio of DNA to transfection reagent for RFL6 cell line?
Thank you in advance..
