Absolute values of transgene (luciferase) expression in (A) PC3 and (B) PC3-PSMA cells with PEI25k-GNRs and PAE-GNRs at an optical density of 0.0025 a.u. loaded with different amounts of pGL3 plasmid DNA (ng). Transgene (luciferase) expression in (C) PC3 and (D) PC3-PSMA reported relative to PEI25k-GNRs (* p<0.05; ** p<0.01; Student t-test). Luciferase expression, in relative luminescence units (RLU) was analyzed 48 h post transfection and normalized to total protein content (mg) resulting in RLU /mg values.
