WebFluorescein isothiocyanate ( FITC) is a derivative of fluorescein used in wide-ranging applications [1] [2] including flow cytometry. First described in 1942, [3] FITC is the original fluorescein molecule functionalized with an isothiocyanate reactive group (−N=C=S), replacing a hydrogen atom on the bottom ring of the structure. WebFluorescein derivatives are the most common fluorescent reagents for biological research because of their high absorptivity, excellent fluorescence quantum yield, and good water solubility.
