(A) Cytotoxicity of chitosan, PEI and PLL, and (B) χ/M-VLP on HEK293 cells. Metabolic activity measured after 4 h in the presence of polymer or vector was normalized to control cells with no polymer. (C) Transfection of HEK293 cells at vector doses of 1–4 × 109 M-VLP/well in a 12-well plate. (n = 3, error bars represent standard deviation).
