mPEG-DMA

Methoxy-poly(ethylene glycol)-N,N-Ditetradecylacetamide (mPEG-DMA) is an amphiphilic PEG lipid combining a di-C14 alkyl amide anchor with a defined-length hydrophilic PEG segment. Discrete chain lengths with different degrees of polymerization are available. The methoxy cap avoids introducing an additional conventional conjugation site at the hydrophilic chain end, allowing PEG chain length to serve as an independent variable in surface-layer design. 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.
