产品描述

Fluorescein biotin (FITC biotin) is a fluorescent biotin derivative and avidin and streptavidin ligand that contains a FITC fluorophore which displays excitation/emission maxima of 485/535 nm, respectively. FITC fluorescence is quenched upon binding to avidin or streptavidin and decreases in fluorescence intensity have been used to quantify biotin binding stoichiometry.
