Expression of siRNA against HeLa cells stably expressing GFP delivered by SV40 pseudovirions and by lipid transduction. HeLa cells stably expressing GFP (red) were transduced with a full reaction of the mix of in vitro packaged siGFP-1 and siGFP- 2 via SV40 pseudovirions (green). The majority of the cells ceased GFP expression, while lipid-transfected siRNAs - siGFP-1 and siGFP-2 cells showed much higher expression (blue). Cells were analyzed three days post-transduction.
