    • This invention provides compositions and methods for assaying the presence of a target analyte in a sample using a solid support. Embodiments of the present invention provide a solid support having a binding protein, such as an antibody, antibody fragment or protein receptor, immobilized to the solid support and at least two separate nucleic acid primers immobilized near the binding protein. This invention also provides a method for tethering two or more polypeptide subunits to generate a multifunctional fusion protein, which can have a primary function, e.g., binding a target analyte, such as a target protein, or an enzymatic activity, and one or more of the subunits of the fusion protein carries out a secondary function, e.g., capture on a solid matrix or quantitation.
    • 本发明提供了使用固体支持物来测定样品中目标分析物的存在的组合物和方法。 本发明的实施方案提供了固体支持物,其具有固定在固体支持物上的结合蛋白,例如抗体,抗体片段或蛋白受体,以及固定在结合蛋白附近的至少两个分开的核酸引物。 本发明还提供了一种用于束缚两个或更多个多肽亚基以产生多功能融合蛋白的方法,所述多功能融合蛋白可具有主要功能,例如结合目标分析物如靶蛋白或酶活性,以及​​一种或多种 融合蛋白的亚基执行次要功能,例如在固体基质上捕获或定量。
