Effect of FA-PEG modification of cationic liposomes on suppression of luciferase expression in KB-Luc cells after transfection with FA-PEG-modified siRNA lipoplexes. (A) LP-HAPC-1–3mol%PEG2000 and LP-HAPC-1–3mol%FA-PEG2000, (B) LP-HAPC-1mol%PEG5000 and LP-HAPC-1mol%FA-PEG5000, (C) LP-OH-1–3mol%PEG2000 and LP-OH-1–3mol%FA-PEG2000, (D) LP-OH-C-1–3mol%PEG2000 and LP-OH-C-1–3mol%FA-PEG2000 were used. The siRNA lipoplexes with Cont siRNA or Luc siRNA were added to KB-Luc cells at 50 nM siRNA, and the luciferase assay was carried out 48 h after incubation. Each column represents the mean + SD (n = 3). ** p < 0.01, compared with Cont siRNA.
