Biotin-PEG-DSPE

Biotin-poly(ethylene glycol)-1,2-Distearoyl-sn-glycero-3-phosphoethanolamine (Biotin-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. Biotin can bind avidin or streptavidin. The PEG spacer separates the recognition unit from the immobilization surface. 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.
