(a) Confocal microscopic image of GFP expression 48 h post transfection in ARPE-19 cell line under serum-free and 10 % serum transfection media. Transfection of G4/ECO/pDNA N/N/P ratios 2/1/1, 2/2/1, 2/3/1, 3/1/1, 3/2/1 and 3/3/1 nanoparticles were evaluated. (b) Flow cytometry of GFP expression 48 h post transfection of ARPE-19 cell line under serum-free and 10 % serum transfection media. G4/ECO/pDNA nanoparticles were tested over a range of N/N/P ratios with lipofectamine 2000, ECO/pDNA particles and G4/pDNA particles used as controls.
