Glyco-poly-L-lysine is better than liposomal delivery of exogenous genes to rat of liver

Figure 2 Determination of the optimal proportion of G-PLL bound to plasmid by 1% agarose 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 plasmid. Plasmid 1 μg could only been bound completely by more than 0.4 μg G-PLL.
