What is DODMA?

Description

1,2-Dioleyloxy-3-dimethylamino-propane (DODMA) is a cationic lipid containing the unsaturated long-chain (18:1) oleic acid inserted at both the sn-1 and sn-2 positions. It has been used in the composition of liposomes formulated as stable nucleic acid lipid particles that can encapsulate siRNA or other small molecules to be used for drug delivery.

Chemical properties

DODMA is a colourless to light yellow liquid; soluble in ethanol, DMSO, DMF; stored at -20℃.

The Uses of DODMA

DODMA is responsible for the formation and morphology of lipid nanoparticles containing ionizable cationic lipids and siRNA useful for silencing disease-?causing genes in hepatocytes following i.v. administration.

The Uses of DODMA

1,2-Dioleyloxy-3-dimethylamino-propane is a cationic lipid containing the unsaturated long-chain (18:1) oleic acid inserted at both the sn-1 and sn-2 positions. It has been used in the composition of lipospomes formulated as stable nucleic acid lipid particles that can encapsulate siRNA or other small molecules to be used for drug delivery.[Cayman Chemical]

What are the applications of Application

DODMA is suitable for use in the preparation of lipid nanoparticles (LNPs).

Biochem/physiol Actions

DODMA (1,2-dioleyloxy-3-dimethylaminopropane) is used in the preparation of cationic liposomes and lipid nanoparticles (LNPs). LNPs with DODMA has low or neutral zeta potential. DODMA is efficient in encapsulating nucleic acid during synthesis by reducing the physiological pH. DODMA is implicated in gene therapy.
