Figure 2. Effect of Bcl-2 levels on transfection activity of pDNA complexes.

Figure 2

(a) Luciferase expression. Cells were transfected for 4 h with 0.5 μg pDNA complexed with PLL or rPLL (N:P 2) to which DOTAP was added to form ternary complexes. Luciferase expression was measured after 24 h as mean RLU/mg cellular protein (n=3). Redox/Non-redox is the ratio (± SD) of transfection activity of rPLL-to-PLL complexes. Secondary axis (●) shows transfection in RLU/mg cellular protein mediated by rPLL complexes in the absence of serum. (b) eGFP expression. Cells were transfected with eGFP pDNA as described above and the gene expression was measured 48 h after transfection as mean % GFP positive cells (n=3). Redox/Non-redox is the ratio (± SD) of transfection activity of rPLL-to-PLL complexes. Secondary axis (●) shows % of GFP positive cells mediated by rPLL complexes in the absence of serum.
