Disclosed are sensitive methods for detecting a target substance in low concentrations. The method can include immobilizing a target substance to a solid phase; incubating the immobilized target substance with a reporter enzyme detection probe in solution under conditions for forming target: enzyme detection probe complexes; washing the solid phase to remove any unbound reporter enzyme detection probe; incubating the target: enzyme detection probe complex with a reporter enzyme detection probe substrate in substrate reaction solution to generate one or more ionizable products; and detecting one or more of the one or more ionizable products using mass spectrometry (MS).
本发明涉及一种敏感的低浓度目标物检测方法。该方法可以包括将目标物质固定到固相上;在形成目标物:酶检测探针复合物的条件下,将固定的目标物质与溶液中的报告酶检测探针孵育;洗涤固相以去除任何未结合的报告酶检测探针;将目标物:酶检测探针复合物与报告酶检测探针底物在底物反应溶液中孵育,以产生一个或多个可离子化产物;并使用质谱(MS)检测一个或多个可离子化产物中的一个或多个。
