Disclosed is an assay for detecting an analyte. The method includes the steps of contacting a solution suspected of containing the analyte with capture antibodies specific for the analyte, wherein analyte contained in the solution is captured by the capture antibodies. Then contacting the capture antibodies with a solution containing the analyte attached to an alcohol oxidase (AOX) enzyme, to yield captured, labeled analyte. Then contacting the capture antibodies with a reagent mixture that generates a first signal proportional to the captured, labeled analyte and quantifying the first signal. And then measuring concentration of the analyte in the unknown sample by comparing the first signal to standard curve of signals. The assay can be implemented in an ELISA format.
本发明涉及一种检测分析物的测定方法。该方法包括以下步骤:将疑似含有分析物的溶液与特异性捕获分析物的捕获
抗体接触,其中溶液中的分析物被捕获
抗体捕获。然后,将捕获
抗体与连接有醇氧化酶(AOX)酶的分析物的溶液接触,以得到捕获的标记分析物。接着,将捕获
抗体与产生与捕获的标记分析物成比例的第一信号的试剂混合物接触,并对第一信号进行定量测量。最后,通过将第一信号与信号标准曲线进行比较,测量未知样品中分析物的浓度。该测定方法可以在ELI
SA格式下实施。
