Expression of β-galactosidase activity and persistence of fluorescent liposome- pLacZ complexes in mice calf muscles. Mice calf muscles were histochemically stained for β-galactosidase activity at the day 1 (A) and at the day 28 (B) after i.m. injection of 10 μg pLacZ followed by electroporation. Histological detection of fluorescent liposome-pDNA complex (10 μg pLacZ/CDAN:PE-rh) in mice calf muscles at the day 1 (C) and 28 (D) after administration into young mice (the age of 5 weeks).
