Preparation and property analysis of a hepatocyte targeting pH-sensitive liposome

Figure 4 Effect of copresence of 20 mmol/L galactose (A) and glucose (B) on transfection activity of liposomes of different composition in HepG2 cells. Cells were transfected with DNA/ liposome complexes in the presence (□) and absence (■) of galactose or glucose. A fixed amount (0.4 μg/well) of plasmid DNA was complexed with liposomes at a ratio of 1:5 (wt/wt). Each value represents ^-x±s (n = 3).
