DSPE-PEG-Biotin (MW 2000)（Cat No.:I015839）is an amphiphilic phospholipid-PEG conjugate designed for targeted delivery, biomolecular labeling, and affinity-based applications. It contains a hydrophobic DSPE (1,2-distearoyl-sn-glycero-3-phosphoethanolamine) anchor, a PEG2000 spacer for solubility and flexibility, and a biotin group that binds strongly to streptavidin or avidin systems. The PEG chain enhances stability, reduces nonspecific interactions, and prolongs circulation, while DSPE ensures stable incorporation into liposomes, micelles, or other nanostructures. This reagent is widely applied in liposomal drug delivery, imaging, diagnostics, and biosensor development where strong biotin–avidin interactions enable selective and durable conjugation.
