Cationic liposome has been studied as one of the most promising non-viral gene delivery systems. In this report, we describe a new synthesized cholesterolic cationic lipid (2-aminoethylcarbamate-cholesterol) and dioleylphosphatidylethanolamine (DOPE) improve the cellular uptake properties of antisense ODNs, as well as plasmid DNA with low toxicity. This formulation of cholesterolic cationic lipid termed Chol-E, efficiently transfects ODNs and plasmids into many cell types in the presense or absence of 10% serum in the medium.
