This invention relates to novel tracers and their synthesis and use in an immunoassay for the detection of controlled drugs such as amphetamine (APM), methamphetamine (MAPM) and their derivatives, in a biological or aqueous sample. In particular, this invention provides methods for synthesizing novel tracers in which a non-controlled substance is both the starting material in tracer synthesis and the binding site on the resulting novel tracer for the antibody, thereby eliminating the necessity of using controlled substances as starting materials. In addition, the novel tracers of the present invention can be used as an analyte analog in an immunoassay, such as a continuous flow displacement immunoassay. It was unexpectedly discovered that the novel tracers of the present invention substantially improve the performance of the continuous flow displacement immunoassay as compared with conventionally designed tracers.
这项发明涉及新型示踪剂及其合成和在生物或水样中检测控制药物(如苯丙胺(APM)、甲基苯丙胺(MAPM)及其衍生物)时的应用的方法。具体来说,本发明提供了合成新型示踪剂的方法,其中非受控物质既是示踪剂合成的起始物质,又是结果新型示踪剂上的抗体结合位点,从而消除了使用受控物质作为起始物质的必要性。此外,本发明的新型示踪剂可以作为免疫测定中的分析物类似物,如连续流位移免疫测定。令人意外地发现,与传统设计的示踪剂相比,本发明的新型示踪剂显著提高了连续流位移免疫测定的性能。
