Application
FITC-Dextran wird für die Herz-Kreislauf-, Mikrozirkulations-, Perfusions-, Zellmonolayer- und Zellmembranpermeabilitätsforschung als fluoreszierender Flusstracer zur Messung von Prozessen wie Durchblutung, Membranschädigung, vaskuläre Drainage und renale Elimination eingesetzt.
Fluorescein-Isothiocyanat–Dextran (FITC-Dextran 4) wird als Fluoreszenzsonde zur Untersuchung der Zellpermeabilität eingesetzt. FITC-Dextran 4 wird zur Untersuchung der Permeabilität von Epithelzellen wie Intestinal- und Renalzellen in vivo eingesetzt.

Are there any fluorescent hydrophobic substitutes of similar size to FITC dextran (4,000 amu) available, considering regular dextran lacks fluorescence and is hydrophilic?
1 answer-
There is only one dextran conjugated with a hydrophobic fluorescent dye. The TRITC dextran, T4037, has an average dextran weight of 4,400 amu and TRITC is slightly more hydrophobic than FITC.
