Dimethyldioctadecylammonium (bromide)

Dimethyldioctadecylammonium (DDA) is a cationic lipid widely used to formulate liposomal vaccine adjuvants, enhancing antigen presentation and cellular immunity in preclinical models. Its application extends to fundamental biophysical studies of membrane dynamics and as a delivery vehicle for mycobacterial antigens in tuberculosis research, demonstrating efficacy in reducing bacterial loads in animal infection models.
