Description
General Description
DODAP (1,2-Dioleoyl-3-dimethylammonium-propane) is an ionizable cationic lipid containing two oleoyl (C18:1) hydrocarbon chains and a tertiary amine headgroup. Due to its pH-responsive ionization behavior, DODAP is widely used in lipid nanoparticle (LNP) formulations for the encapsulation and intracellular delivery of nucleic acids.
DODAP-containing formulations can facilitate efficient RNA, DNA, siRNA, and oligonucleotide delivery while maintaining favorable biocompatibility and formulation stability.
