What is DODAP?
Description
DODAP (18:1) is an ionizable cationic lipid with lower cytotoxicity and high transfection efficiency. DODAP is neutral at physiological pH, but acquires a positive charge inside the endosome due to the protonation of free amines when pH is lower than its pKa (<7).
Chemical properties
Light Yellow Oil
The Uses of DODAP
Cationic amphiphiles are being studied for their potential role in preparing liposomes for interaction with artificial and biological membranes and cellular transfection techniques. Cationic species with ester linkages to the hydrophobic portion are more easily degraded by recipient cells and more efficiently metabolized.
