Chemicals & Small Molecules

FITC-Dextran (MW 60,000-76,000) is a fluorescein isothiocyanate (FITC)-labeled dextran fluorescent probe that is commonly used as a tracer molecule to label and track the action of cells or other biomaterials on semipermeable membranes.

FITC-Dextran (MW 2,000,000) is a fluorescent dye-based compound that can be used for short cycle durations to outline blood vessels.FITC-Dextran (MW 2,000,000) is involved in the quantification of BBB leakage, and can be used in conjunction with a confocal microscope to visualize blood-brain-barrier leakage.
