DSPE (1,2-distearoyl-sn-glycero-3-phosphoethanolamine) is an 18 carbon phospholipid that is highly hydrophobic. PEG backbone, on the other hand, offers good hydrophilicity and water solubility. Carboxylic functionalized DSPE PEG has excellent reactivity towards amine or hydryoxyl groups. Carboxylic PEG DSPE is one of most commonly used reactive phospholipids to conjugate antibodies,peptides or other ligands to the surface of liposome and other lipid nanoparticles. Pegylation of phospholipids significantly increases the blood circulation time and stability for encapsulated drugs. ruixibio has developed a comprehensive collection of reactive phospholipid PEG products that have high purity, various molecular weights and excellent chemical reactivity. These lipid PEG conjugates demonstrate excellent amphilphilic properties and offer superior advantages for small and large molecule labeling, formulation and delivery. Handling and Use: DSPE PEG acid should always be kept in low temperature in dry condition. Prepare fresh solution right before use.Avoid frequent thaw and freezing.
