A method for detecting an analyte of interest in a sample includes the steps of binding the analyte to the surface of a substrate through a biotin-biotin binding protein interaction, contacting the surface-bound analyte with a quantitatively detectable analyte-binding moiety that binds thereto, measuring the quantity of detectable moiety bound to the substrate surface (11) and deriving therefrom the quantity of analyte in solution. A preferred use for the present method is in conjunction with a piezoelectric surface transverse wave device.
一种检测样品中感兴趣的分析物的方法包括以下步骤:通过生物素-生物素结合蛋白的相互作用将分析物与基质表面结合;将表面结合的分析物与定量检测的分析物结合分子接触;测量与基质表面结合的可检测分子的数量(11),并由此得出溶液中分析物的数量。本方法最好与压电表面横波装置结合使用。
