A method for determining an analyte in a sample suspected of containing the analyte comprises providing in combination a medium, the sample, and two or more different receptors. Each different receptor binds to at least two different epitopic sites. One of the epitopic sites is a common binding site and one of the epitopic sites is non-common binding site. The non-common epitopic sites are different for each different receptor. The receptors exhibit mono-molecular binding. The medium is incubated under conditions for binding of the receptors to the epitopic sites. The medium is examined for the presence and/or amount of complexes comprising the epitopic sites and the receptors. The presence and/or amount of the complexes indicate the presence and/or amount of the analyte in the sample.
一种用于确定疑似含有分析物的样品中分析物的方法,包括结合提供介质、样品和两种或两种以上不同的受体。每个不同的受体至少与两个不同的表位结合。其中一个表位是普通结合位点,另一个表位是非普通结合位点。每个不同受体的非共用表位点都不同。受体呈现单分子结合。
培养基在受体与表位结合的条件下进行培养。检测
培养基中是否存在由表位点和受体组成的复合物和/或复合物量。复合物的存在和/或数量表明样品中分析物的存在和/或数量。
