    • 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. Cleavage of the polyphosphate product of phosphoryl transfer via phosphatase leads to a detectable change in the label attached thereon. When the polymerase assay is performed in the presence of a phosphatase, there is provided a convenient method for real-time monitoring of DNA or RNA synthesis and detection of a target nucleic acid.
    • 本发明涉及使用标记的底物或底物类似物检测靶的改进方法。 所述方法包括在酶催化的反应中使底物或底物类似物反应,其仅在这种底物或底物类似物反应时产生具有独立可检测信号的标记部分。 本发明特别地描述了基于使用末端磷酸酯标记的核苷酸作为核酸聚合酶的底物来检测样品中核酸的方法。 本发明提供的方法利用了具有比色染料,化学发光或荧光部分的核苷多磷酸,双脱氧核苷多聚磷酸酯或脱氧核苷多聚磷酸酯类似物,连接至末端磷酸酯的质量标签或电化学标签。 当核酸聚合酶使用该类似物作为底物时,酶活性标记将存在于磷酸转移的无机多磷酸盐副产物上。 通过磷酸酶切割磷酸转移的多磷酸盐产物导致附着在其上的标签的可检测的变化。 当在磷酸酶的存在下进行聚合酶测定时,提供了用于实时监测DNA或RNA合成和检测靶核酸的方便的方法。
