Title: Labeled reagents for use in immunoassays and fluorescent compounds and complexes used therein

Abstract: Disclosed are labeling reagents containing fluorescent compounds represented by the general formula ##STR1## where R is a group capable of combining with proteins, Ar is a conjugated double bond system, and n is a whole number. These labeling reagents have high fluorescence emission intensities, give high synthesis yields, permit both solid-phase measurements and liquid-phase measurements in immunoassays, and require less measuring steps.
