Comparison between intravenous and peritoneal route on liver targeted uptake and expression of plasmid delivered by Glyco-poly-L-lysine

Figure 1 Determination of optimal proportion of G-PLL bound to plasmid by 1% agar ose electrophoresis. Lane 1-8 are respectively 0.05 μg, 0.1 μg, 0.2 μg, 0.3 μg, 0.4 μg, 0.5 μg, 1.0 μg, and 1.5 μg G-PLL mixed with 1 μg pTM/MMP-1 p lasmid. pTM/MMP-1 1 μg plasmid could only be bound completely by more than 0. 4 μg G-PLL.
