More info

1,2-Distearoyl-sn-Glycero-3-Phosphoethanolamine (DSPE)-polyethylene glycol with conjugated cyanine 3 (DSPE-PEG-Cy3) is an
amphiphilic polymer. Pegylated phospholipids are excellent liposome formation materials that can be used for drug delivery, gene
transfection and vaccine delivery as well. Pegylation of phospholipids significantly improves the blood circulation time and stability
for encapsulated drugs. These materials can also be used for targeted drug delivery by modifying their surfaces with targeting
ligands such as antibodies and peptides.
