Application

Dextran labeled with fluorescein isothiocyanate for possible use in perfusion studies in animals.
Fluorescein isothiocyanate–dextran (FITC-Dextran 150) is use as a fluorescent probe to study cell permeability. FITC-Dextran 150 is useful to study processes that affect the permeability of the blood brain barrier (BBB) and microvascular structures. FITC-Dextran 150 is used in fluorescence microlymphography.

Other Notes

Commonly utilized as a macromolecular fluorochrome in inflammatory studies
