A method for performing a multiplexed diagnostic assay, such as for two or more different targets in a sample, is described. One embodiment comprised contacting the sample with two or more specific binding moieties that bind specifically to two or more different targets. The two or more specific binding moieties are conjugated to different haptens, and at least one of the haptens is an oxazole, a pyrazole, a thiazole, a nitroaryl compound other than dinitrophenyl, a benzofurazan, a triterpene, a urea, a thiourea, a rotenoid, a coumarin, a cyclolignan, a heterobiaryl, an azo aryl, or a benzodiazepine. The sample is contacted with two or more different anti-hapten antibodies that can be detected separately. The two or more different anti-hapten antibodies may be conjugated to different detectable labels.
本文描述了一种进行多重诊断检测的方法,例如针对样品中两个或多个不同靶点的检测。其中一个实施方案包括用两个或两个以上特异性结合分子与样品接触,这些特异性结合分子与两个或两个以上不同的靶标特异性结合。这两种或两种以上特异性结合分子与不同的抗原共轭,其中至少一种抗原是噁唑、吡唑、噻唑、二硝基苯以外的硝基芳基化合物、苯并呋喃、三萜、脲、硫脲、类橙皮甙、香豆素、环木脂素、杂芳基、偶氮芳基或苯并二氮杂卓。样品与两种或两种以上可分别检测的不同抗链肽抗体接触。两种或多种不同的抗链肽抗体可与不同的可检测标签连接。
