We evaluated the transfection efficiency of five different cationic liposome/plasmid DNA complexes, during the in vitro gene transfer into human epithelial tracheal cell lines. A dramatic correlation between the transfection efficiency and the charge ratio (positive charge of liposome to
Cationic liposomes are being utilized for the delivery of DNA into mammalian cells both in vitro and in vivo. In this report, we describe a rapid, simple injection method for the preparation of cationic liposomes that requires no special equipment.
An attempt was made to use simple cationic liposomes DC-Chol/DOPE and DDAB/DOPE (DC-Chol is 3 beta (N(N',N-dimethylaminoethane) carbamoyl) cholesterol, DDAB is dimethyldioctadecyl ammonium bromide and DOPE is dioleoylphosphatidylethanolamine) for transfer of Escherichia coli cytosine deaminase 'suicide' gene under the control
Clinical trials using cationic liposome-mediated DNA transfer have now been initiated for several disorders including cystic fibrosis. Previous studies have shown that the level of gene expression achieved may be dependent on the formulation of the DNA-liposome complex and the
