HOOCCH2CH2-PEG-DPPE

Carboxylic acid-poly(ethylene glycol)-1,2-Dipalmitoyl-sn-glycero-3-phosphoethanolamine (COOH-PEG-DPPE) is an amphiphilic PEG lipid combining a di-C16 acyl phospholipid anchor with a defined-length hydrophilic PEG segment. Discrete chain lengths with different degrees of polymerization are available. The carboxyl group can be activated for amide coupling with primary-amine-containing molecules, retaining a handle for subsequent ligand or carrier attachment. 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.
