The present invention is directed to a fluorescent polarization assay for salicylate, to the various components needed for preparing and carrying out such an assay, and to methods of making these components. Specifically, tracers, immunogens and antibodies are disclosed, as well as methods for making them. The tracers and the immunogens are made from substituted benzoic acid compounds. A fluorescein moiety is included in the tracer, while a poly(amino acid) forms a part of the immunogen. The antibodies are prepared in response to the immunogen. The assay is conducted by measuring the degree of polarization retention of plane polarized light that has been passed through a sample containing antiserum and tracer.
本发明涉及水杨酸盐的荧光偏振测定法、制备和进行这种测定法所需的各种成分以及制备这些成分的方法。 具体而言,本发明公开了示踪剂、免疫原和抗体以及制备它们的方法。 示踪剂和免疫原是由取代的苯甲酸化合物制成的。 示踪剂中含有荧光素分子,而聚氨基酸则是免疫原的一部分。 抗体是针对免疫原制备的。 该测定法是通过测量穿过含有抗血清和示踪剂的样品的平面偏振光的偏振保留程度来进行的。
