CB-PEG-DMG

Carboxybetaine-poly(ethylene glycol)-Dimyristoylglycerol (CB-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 carboxybetaine provides a carboxylate-based zwitterionic headgroup for comparing the relationship between acidic-group type and interfacial presentation. 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.
