Background:

FITC-Dextran is a marker consisting of coupling fluorescein-isothiocyanate to dextran. FITC-Dextrans are polysaccharides comprised of varying lengths of branched glucose molecules which available in molecular weights ranging from 4-70 kDa and can be used to determine solute, ion and protein permeability of the blood-brain barrier (BBB) based on the size of the dextran used[1][2][3].
