OAc-PEG-DSPE

Acetoxy-poly(ethylene glycol)-1,2-Distearoyl-sn-glycero-3-phosphoethanolamine (OAc-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 acetate temporarily masks the hydroxyl group. Appropriate deprotection restores the opportunity for further hydroxyl derivatization. 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.
