BP Lipid 209 is an amine lipid which has a 9-carbons lipid tail on the primary ester. Both esters are located at C8 and C10 position relative to the amine nitrogen. The head contains ethanolamine which can efficiently encapsulate mRNA. The lipid can be used to prepare mRNA nanocarriers with good balance of delivery efficiency and pharmakokinetics as well as rapid lipid clearance profile. Reagent grade, for research purpose.
