1,2-Distearoyl-sn-Glycero-3-Phosphoethanolamine (DSPE) conjμgated Polyethylene Glycol, DSPE PEG is a phospholipid PEG conjμgate which has both hydrophilicity and hydrophobility. Pegylated phospholipids are excellent liposome formation materials that can be used for drμg delivery, gene transfection and vaccine delivery as well. Pegylation of phospholipids significantly improves the blood circulation time and stability for encapsulated drμgs. These materials can also be used for targeted drμg delivery by modifying their surfaces with targeting ligands such as antibodies, peptides.
