Electrophoretic gel retardation assay of pMMP7-GFP in the absence and presence of co-liposomes at different N/P ratios (0–8). The lipids of C12 (A–E) and C16 (F−J) chain lengths and PE were used to measure their DNA-binding abilities by gel electrophoresis assay. The molar ratio of synthetic lipid and PE was 1:1 (mole ratio). All of the gel electrophoresis measurements were performed in triplicates.
