DOTAP methylsulfate

Description

DOTAP methylsulfat is a cationic lipid reagent, a cationic derivative of trimethylammonium, linked to two 18-carbon fatty acid tails, each with a single olefin group. DOTAP methylsulfat can self-assemble with negatively charged ions such as DNA to form complexes, which can be adsorbed to the cell membrane surface and enter the cell by electrostatic interaction and endocytosis, respectively. DOTAP methylsulfat promotes endosomal membrane fusion with its own hydrophobic domain, releases DNA into the cytoplasm, and exerts gene delivery function. DOTAP methylsulfat can be widely used in research fields such as gene therapy, cell transfection, and non-viral vector design 1 2 .
