1,2-Dioleoyl-3-trimethylammonium-propane, Chloride (DOTAP)

Cationic liposome-forming compound for transfection of DNA, RNA and other negatively charged molecules into eukaryotic cells. Mixing DOTAP with DNA results in spontaneously formed stable complexes that can be directly added to cell culture medium. These complexes fuse with the cell membrane and release DNA into the cytoplasm. The cells are transfected efficiently without cytotoxic effects. Use approximately 5-10ug DOTAP per ug DNA and approximately 10-20ug DOTAP per ml cell culture medium. The optimal working concentration and transfection time depends in part on the cell line used, and the type of material (RNA, DNA, protein) loaded.
