Negative-staining electron micrographs of liposomes (EPC/DOPE/DOTAP 50:25:25% molar). A and B represent empty (water- containing) liposomes; C and D represent liposome entrapping DNA at a 10:1 molar charge ratio (cationic lipid:DNA); E and F represent liposomes complexing DNA at the same molar charge ratio. Bars indicate: A, C, E – 1000 nm; B, D, F – 200 nm.
