Abstract Background The aim of this study was to determine the optimal non-viral transfection method for use in human smooth muscle cells SMC and endothelial cells EC . Methods Coronary Artery CoA and Aortic Ao SMC and EC were transfected with a reporter plasmid encoding chloramphenicol acetyltransferase type 1 CAT with seven different transfection reagents two electroporation methods and a photochemical internalization PCI method. CAT determination provided information regarding transfection efficiency and total protein measurement was used to reflect the toxicity of each method. Results Electroporation via the nucleofector machine was the most effective method tested. It exhibited a 10 to 20 fold for SMC and EC respectively increase in transfection efficiency in comparison to the lipofection method combined with acceptable toxicity. FuGene 6 and Lipofectamine PLUS were the preferred transfection reagents tested and .
