Phosphate-PEG-DSPE

Phosphate monoester-poly(ethylene glycol)-1,2-Distearoyl-sn-glycero-3-phosphoethanolamine (Phosphate-PEG-DSPE) is an amphiphilic PEG lipid combining a di-C18 acyl phospholipid anchor with a defined-length hydrophilic PEG segment. Discrete chain lengths with different degrees of polymerization are available. The phosphate monoester presents a phosphorus-containing ionic site at the hydrophilic chain end for studies of interfacial hydration and ionic interactions. It can be used to construct interfaces in membrane-related systems and nanoparticle formulations, enabling comparisons of anchoring structure, hydrophilic chain length, terminal functionality, and formulation dispersion.
