Description Phosphatidylethanolamine (PE) is one of the widely distributed glycerophospholipid in eukaryotic cells. 1,2-dilauroyl-sn-glycero-3-phosphoethanolamine (12:0 PE/DLPE) possess an ammonium head group (RNH3+) and has alkyl chains made of 11 carbon atoms. Application 1,2-dilauroyl-sn-glycero-3-phosphoethanolamine (12:0 PE): has been used as a lipid standard in the optimization of the liquid chromatography−mass spectrometry (LC-MS) method conditions, may be used as a phospholipid (PL) standard to quantify phosphatidylethanolamine (PE) from plant lipids, may be used to prepare anionic liposomes, may be used to prepare binary giant unilamellar vesicles (GUVs).
