General description

18:0 DDAB is cationic lipid and a quaternary ammonium salt. The hydrocarbon tails are saturated unlike the ionizable lipids.

Application

18:0 DDAB is suitable for the preparation of lipid-nanoparticles. It has also been used as an adjuvant and combined with monophosphoryl lipid A (MPL) for immunizing mice.

Biochem/physiol Actions

18:0 DDAB is a surface-active molecule, used as an adjuvant to induce systemic immune response. It is non-toxic.

Major impediments to developing a Chlamydia vaccine lie in identifying immunologically relevant T-cell antigens and delivery in a manner to stimulate protective immunity. Using an immunoproteomic approach, we previously identified three immunodominant Chlamydia T-cell antigens (PmpG-1, PmpE/F-2, and RplF). Because
