The effect of pIL-4/GFP encapsulation on size and zeta potential was determined by agarose gel electrophoresis and zetasizer assays. Results of agarose gel reaction for pIL-4/GFP in PEI4C16 liposome showed in the lanes at different N/P ratios (A). The size and zeta potential of the modified PEI4C16 liposome at different N/P ratios showed in (B). The increase in size and decrease in zeta potential were associated to the elevation of pIL-4/GFP loading. For pIL-4/GFP concentration, N/P ratio at 1/1 includes 0.2 µg plasmid.
