Used as a lipid-based transfection reagent in molecular biology for efficient delivery of nucleic acids into cells. Its amphiphilic structure enables self-assembly into micelles or liposomes that encapsulate DNA or RNA, protecting them from degradation and facilitating cellular uptake. Commonly applied in gene expression studies, RNA interference, and recombinant protein production. Also explored in non-viral gene therapy due to low cytotoxicity and high stability in physiological conditions. Effective in both adherent and suspension cell lines, including hard-to-transfect primary cells.
