Fluorescein isothiocyanate–dextran (FITC-Dextran 70) is use as a fluorescent probe to study cell processes such as cell permeability, phagocytosis and endocytosis and to study mechanisms of biomolecular delivery. FITC-Dextran 70 may be used to study the capacity, selectivity and efficiency of encapsulation and release by drug delivery vehicles.
Dextran labeled with fluorescein isothiocyanate for possible use in perfusion studies in animals.
