    • Provided is a composition comprising an analyte bound covalently or through a first binding pair to a polymer. In this composition, the analyte is less than about 2000 MW; the polymer further comprises more than one signal or first member of a second binding pair; and the analyte is not a member of the first binding pair or the second binding pair. Also provided is an assay for an analyte. The assay comprises: combining a sample suspected of containing the analyte with the above-described composition and a binding agent that binds to the analyte; and detecting the signal or the first member of the second binding pair that is bound to the binding agent. In this assay, the amount of the signal or the first member of the second binding pair bound to the binding agent is inversely proportional to the analyte in the sample. Additionally provided is a multisignal labeling reagent comprising a first polymer covalently bound to (a) a reactive group or a first member of a first binding pair, and (b) more than one digoxigenin molecule.
    • 提供了包含共价键合或通过第一结合对与聚合物结合的分析物的组合物。 在该组合物中,分析物小于约2000MW; 聚合物还包含多于一个信号或第二结合对的第一个成员; 并且分析物不是第一结合对或第二结合对的成员。 还提供了分析物的测定。 该测定包括:将怀疑含有分析物的样品与上述组合物结合,和结合分析物的结合剂; 以及检测绑定到绑定剂的第二绑定对的信号或第一成员。 在该测定中,与结合剂结合的信号或第二结合对的第一个成员的量与样品中的分析物成反比。 另外提供了包含共价结合到(a)第一结合对的反应性基团或第一个成员的第一聚合物的多信号标记试剂,和(b)多于一个的地高辛分子。
