Transfer of the functional genes into eucaryotic cells by neutral phospholipid liposomes

: Transfection of plasmid DNAs containing b-galactosidase gene (pQE-LacZ) or alkaline phosphatase (pCSEAP) into L929 cell line using was studied. The complexes between plasmid DNA and liposomes containing Ca ions and glycyrrhizic acid or &-tocopherol caused successful transfection of functional genes into L929 cells. The efficiency of transfection of plasmid DNAs into L929 cells using polynucleotide-metallo(II)-liposome complexes were 30-50% from the efficiency value of calcium phosphate coprecipitation transfection.
