(A) Flow cytometry quantification of GFP plasmid transfection by Base and Guan copolymer polyplexes at various N/P ratios to cultured HeLa cells. (B) Cytotoxicity of Base and Guan copolymer polyplexes at various N/P ratios to cultured HeLa cells as determined by PI+/− staining. Data shown as mean + SD (Student t-test, *p < 0.04, ** p < 0.001).
