SB-PEG-DMG

Sulfobetaine-poly(ethylene glycol)-Dimyristoylglycerol (SB-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 sulfobetaine combines positive and negative charges within one terminus, enabling comparisons of zwitterionic headgroup hydration and interfacial interactions. 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.
