Mal-N-PEG-DSPE

Directly n-linked maleimide-poly(ethylene glycol)-1,2-Distearoyl-sn-glycero-3-phosphoethanolamine (MAL-N-PEG-DSPE) is an amphiphilic PEG lipid combining a di-C18 acyl phospholipid anchor with a defined-length hydrophilic PEG segment. Discrete chain lengths with different degrees of polymerization are available. The directly N-linked maleimide retains a thiol-reactive site, enabling comparisons of ring attachment modes and resulting conjugate structures. 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.
