Key Benefits of DC-CHOL

Compared to other cationic lipids such as DOTMA or DOTAP, liposomes prepared from DC-Chol and DOPE (at a ratio of 1:1, molar/molar) exhibit only 50% of nanoparticles carrying charge at pH 7. This renders DC-Chol/DOPE liposomes more prone to dissociation compared to DOTAP/DOPE and DOTAM/DOPE liposomes, demonstrating faster mRNA delivery and enhanced cellular transfection efficiency.

DC-CHOL Product Properties

DC-CHOL is a derivative of cholesterol, synthesized through a chemical reaction between dimethylamine and cholesterol. The aminoethylglycine ester formed during its synthesis possesses degradability. It is a commonly used cationic lipid for preparing lipid nanoparticles (LNPs), providing LNPs with positive charge and stabilizing their membrane structure.
