Application

Dextran labeled with fluorescein isothiocyanate for possible use in perfusion studies in animals.
FITC-dextran is used extensively in microcirculation and cell permeability research utilizing microfluorimetry. FITC-dextran has been used to study plant cell wall porosity and capillary permeability. Plasma proteins have been shown not to bind to FITC-dextran.
FITC-dextran is used in cardiovascular, microcirculation, perfusion, cell monolayer and cell membrane permeability research as fluorescent flux tracer compound that supports the measurement of processes such as blood flow, membrane damage, vascular drainage and renal elimination
Fluorescein isothiocyanate–dextran (FITC-Dextran 4) is use as a fluorescent probe to study cell permeability. FITC-Dextran 4 is used with to study permeability of epithelial cell such as intestinal and renal cells in vivo.
