Product Information

Description Dimethyldioctadecylammonium Bromide is a cationic amphipathic lipid. DDA liposomes containing an Ag85B-ESAT-6 antigen induce antigen deposition at an intramuscular or subcutaneous injection site in mice, increasing immune cell exposure to the antigen.
Synonyms DDAB; N,N-dimethyl-N-octadecyloctadecan-1-aminium bromide; 1-Octadecanaminium, N,N-dimethyl-N-octadecyl-, bromide; Dimethyldistearylammonium bromide; Distearyldimethylammonium bromide; Dimethyldioctadecylazanium bromide; Dioctadecyldimethylammonium bromide; di-n-Octadecyldimethylammonium bromide; N,N-Distearyl-N,N-dimethylammonium bromide; 18:0 DDAB; DODAB
