QTMA-Cl-PEG-DMG

Quaternary ammonium chloride-poly(ethylene glycol)-Dimyristoylglycerol (QTMA-Cl-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 quaternary ammonium terminus provides a fixed cationic site, allowing terminal charge and PEG chain length to be studied separately and paired with anionic components. 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.
