SH-PEG-DSPE

Thiol-poly(ethylene glycol)-1,2-Distearoyl-sn-glycero-3-phosphoethanolamine (SH-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 thiol can add to maleimides or participate in disulfide formation, offering different molecular conjugation routes. 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.
