Description

1,2-Distearoyl-sn-Glycero-3-Phosphoethanolamine-PEG-succinic acid (DSPE-PEG-COOH, DSPE-PEG-Acid, N-succinyl-L-α-phosphatidylethanolamine, Distearoyl) is a reactive phospholipid PEG conjugates that can react with primary amine groups. DSPE is an 18 carbon phospholipid that is highly hydrophobic. PEG linker offers good hydrophilicity and water solubility. Carboxylic group (-COOH) on the other PEG terminal reacts with primary amine groups using EDC chemistry. DSPE-PEG thus can be easily incorporated into liposome and other nanoparticles via the reaction of carboxylic acid and amine. DSPE-PEG-COOH is a commonly used reactive phospholipid to conjugate antibodies, proteins, peptides or other substrates to the surface of liposome and other lipid PEG nanoparticles. PEGylated phospholipids have longer blood circulation time and higher stability for encapsulated molecules.
