1,2-distearoyl-sn-glycero-3-phosphoethanolaMine-N-[biotinyl(polyethylene glycol)-2000] (aMMoniuM salt)

DSPE-PEG-Biotin, MW 2,000 is a biotin amphipilic material which forms micelles in an aqueous solution and binds selectively with streptavidin and avidin. This polymer is very promising nanocarriers for therapeutic drug delivery, imaging and molecular labeling.
