Transfection mediated by linear polyethylenimine (25 KDa) (LPEI)-pDNA (1 µg) nanoparticle complexes and branched polyethylenimine (25 KDa) (BPEI)-pDNA nanoparticle complexes at various N/P ratios in (a) HeLa, (b) HEK, (c) COS7 and (d) HepG2. Luciferase activity is shown as means ± STD (n=3, error bars represent standard deviation).
