The field of drug delivery is continuously advancing, with a particular focus on non-viral methods for transporting therapeutic nucleic acids like siRNA and mRNA. Among the various non-viral vectors, cationic lipids play a pivotal role, and DOTMA (CAS 104872-42-6) has established itself as a foundational component. As a dedicated manufacturer and supplier of DOTMA, we provide this essential lipid to researchers and formulators aiming to enhance the efficacy of their nucleic acid-based therapeutics.

DOTMA, chemically known as 1,2-di-O-octadecenyl-3-trimethylammonium propane chloride, is a cationic lipid characterized by its two long unsaturated alkyl chains and a permanently positively charged quaternary ammonium headgroup. This structural feature is critical for its function in nucleic acid delivery. When complexed with anionic nucleic acids, DOTMA forms stable liposomes or lipid nanoparticles (LNPs). The cationic nature of DOTMA is paramount, as it electrostatically binds to the negatively charged phosphate backbone of nucleic acids. This binding condenses the nucleic acid cargo, protecting it from enzymatic degradation in the bloodstream and facilitating its entry into target cells.

The mechanism by which DOTMA facilitates cellular uptake involves interacting with the cell membrane. The positive charge on the liposome surface promotes electrostatic interactions with the anionic components of the cell membrane, leading to endocytosis or direct fusion. This interaction is a key determinant of transfection efficiency, making DOTMA a valuable ingredient for creating effective gene delivery vehicles. Researchers often seek to buy DOTMA for its proven ability to enhance the delivery of genetic material for both therapeutic and research purposes.
