Transfection of PC3-PSMA human prostate cancer cells using EGDE3,3′-PSS-CTAB-GNRs and pEI25-PSS-CTAB-GNRs. PC3-PSMA cells were treated with different concentrations of PE-GNRs containing 350 ng pGL3 plasmid for 6 h. Luciferase expression, in relative luminescence units or RLU was analyzed 48 h following transfection and normalized to protein content in each case (RLU/mg). The normalized luciferase expression for EGDE3,3′-PSS-CTAB-GNRs is reported relative to that for pEI25-PSS-CTAB-GNRs. CTAB-GNRs did not demonstrate any transfection activity at similar optical densities. Asterisks indicate p values < 0.02 determined using two-tailed Student’s t-test for a minimum of three independent experiments.
