Synonyms: Four-Arm polyethylene glycol-DSPE; Four-Arm PEG-DSPE

Four-Arm polyethylene glycol-1,2-distearoyl-sn-glycerol-3-ethanolamine phosphate (4-Arm PEG-DSPE) is a peg derivative with four identical branched chains. It is a white solid or sticky liquid, depending on its molecular weight. It is soluble in warm water, CHCl3, DMSO. DSPE (1,2-distearoyl-sn-glycerol-3-ethanolamine phosphate) is a saturated 18 carbon phospholipid, which is commonly used in the synthesis of liposomes. Polyethylene glycol (PEG)-coupled DSPE is hydrophilic and can be used for drug delivery, gene transfection and biomolecular modification. PEGylation of phospholipids significantly improved the blood circulation time and stability of the capsules.
