The reagent, a cyanine dye, can be used as a label for the determination of proteins with NIR-fluorescent technology. The absorption-maxima of the reagent lies in a region of low interference by other biomolecules. The isothiocyanate-moiety is used to link the reagent to proteins which can sensitively be detected. Experiments to lower the detection-limits of immunoassays have been done.
