Description and Uses

Fluorescein 5-isothiocyanate (5-FITC) is an isomer of fluorescein isothiocyanate (FITC), which is commonly used as a mixture of the 5- and 6-isothiocyanate isomers. It reacts with amine and thiol groups to form conjugates with proteins, lipids, and other molecules for detection by a variety of fluorescent-based applications. 5-FITC displays excitation/emission maxima of 494/519 nm, respectively.

Fluorescein isothiocyanate isomer I has been used for the staining of conidia. It is a kind of fluorescent marker for biochemical applications. Reacts under mild conditions with primary amines and it is also used in modification of actin at lys-61, labelling of FAB and the modification of thiol groups.
