Figure 5.
(a) Epifluorescence microscopy images for T731-GFP cells treated with C3(C16His)2/MOG-siRNA lipoplexes (α = 0.2; ρeff = 4 and 10) and Lipo2000*-antiGFP-siRNA as control, after 72 h of treatment. Images were collected in different channels of fluorescence signals and the overlapping of them. Scale bars are 75 μm. GFP knockdown levels expressed as MFI (unstriped bars, left y-axis) and % GFP (striped bars, right y-axis) in T731-GFP cells at 48 (b) and 72 h (c) of incubation. Cells treated by the lipoplexes were collected at α = 0.2 and ρeff = 4 (light pink bars) and 10 (dark pink bars). Untreated cells were used as a reference of the highest MFI and % GFP value. Free siRNA and Lipo2000*-non-targeting siRNA were used as negative controls (gray and purple bars, respectively) while Lipo2000*-antiGFP-siRNA was used as positive control (blue bars). All experiments were performed with 10% (v/v) of HS. The data represent the mean ± SD of three independent wells.
