cPEG-PEG-DSPE

Cyclic poly(ethylene glycol) bearing a PEG arm conjugated to 1,2-Distearoyl-sn-glycero-3-phosphoethanolamine (cPEG-PEG-DSPE) is an amphiphilic PEG lipid combining a di-C18 acyl phospholipid anchor with a PEG arm pendant from a cyclic scaffold. The pendant arm is available in discrete chain lengths with different degrees of polymerization. The cyclic segment and pendant arm provide distinct topological levels, enabling comparisons of interfacial presentation and assembly with linear materials bearing the same anchor. 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.
