  • Patent number: 7223541
    Abstract: The present invention relates to improved methods of detecting a target using a labeled substrate or substrate analog. The methods comprise reacting the substrate or substrate analog in an enzyme-catalyzed reaction which produces a labeled moiety with independently detectable signal only when such substrate or substrate analog reacts. The present invention, in particular, describes methods of detecting a nucleic acid in a sample, based on the use of terminal-phosphate-labeled nucleotides as substrates for nucleic acid polymerases. The methods provided by this invention utilize a nucleoside polyphosphate, dideoxynucleoside polyphosphate, or deoxynucleoside polyphosphate analogue which has a colorimetric dye, chemiluminescent, or fluorescent moiety, a mass tag or an electrochemical tag attached to the terminal-phosphate. When a nucleic acid polymerase uses this analogue as a substrate, an enzyme-activatable label would be present on the inorganic polyphosphate by-product of phosphoryl transfer.
