Description and Uses

Fluorescein isothiocyanate (FITC) is an amine-reactive derivative of fluorescein dye that has wide-ranging applications as a label for antibodies and other probes, for use in fluorescence microscopy, flow cytometry and immunofluorescence-based assays such as Western blotting and ELISA. The isothiocyanate variety of fluorescein efficiently labels antibodies and other purified proteins at primary amines (lysine side chains)

Excitation wavelength: 494 nm
Emission wavelength: 518 nm
Extinction coefficient: > 70,000 M-1cm-1
Solubility: Soluble in aqueous buffers at pH > 6
Reactive groups: Isothiocyanate, reacts with primary amines at pH 7.0 to 9.0

Fluorescein Isothiocyanate is a fluorescent reagent with incompletely defined position of the NCS. Fluorescein Isothiocyanate is used in multifunctional uniform nanoparticles composed of a magnetite nanocrystal core and a mesoporous silica shell for magnetic resonance, fluorescence imaging. and drug delivery.
