Figure 1

Gel retardation of (A) 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC)/cholesterol (Chol) at a molar ratio of 5:1 lipoplex; (B) DPPC/ dioctadecyldimethylammonium bromide (DOAB) at a molar ratio of 1:1 lipoplex; (C) DPPC/Chol/ DOAB at a molar ratio of 7:2:1 lipoplex; (D) magnetic cationic liposomes/pDNA with different concentrations of magnetite (MAG). pGL3 plasmid and empty liposomes were used as controls. For all panels, (1) is suspension in water, (2) is suspension in ethanol, and (3) is suspension in aqueous solution of plasmid.
