  • Fluorescent detection method and reagent
    Patent number: 7662973
    Abstract: Disclosed is a method for increasing the fluorescence of a Cyanine dye molecule comprising at least one NO2 group characterized by the reduction of the at least one NO2 group to NHOH or NH2 by the action of a nitroreductase. The cyanine dye molecule comprising at least one NO2 group can be used as a substrate for detecting nitroreductase enzyme activity in a composition and allows for the use of a nitroreductase enzyme in an enzyme-reporter system for the detection of analytes, binding reactions or gene expression.
    Type: Grant
