PC-PEG-DMG

Phosphorylcholine-poly(ethylene glycol)-Dimyristoylglycerol (PC-PEG-DMG) is an amphiphilic PEG lipid combining a dimyristoylglycerol anchor with a defined-length hydrophilic PEG segment. Discrete chain lengths with different degrees of polymerization are available. The phosphorylcholine combines phosphorus-containing and quaternary-ammonium structures, providing a building block for membrane-mimetic headgroups and interfacial hydration studies. 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.
