One strategy for improving gene vector properties of polyethylenimine is to facilitate individual transfection mechanism steps. This study investigates (i) improving transfection efficiency by attaching peptide nuclear localization signals (nuclear localization signals: SV40 large T antigen nuclear localization signal or C-terminus of histone H1) to polyethylenimine (10 kDa) and (ii) using disu…
