    摘要: Methods and reagents are disclosed for conducting assays. Embodiments of the present methods and reagents are concerned with chemiluminescent reagents for determining the presence and/or amount of an analyte in a sample suspected of containing the analyte. The reagent is non-particulate and comprises a binding partner for the analyte and a chemiluminescent composition comprising an olefinic compound and a metal chelate. In embodiments of an assay, a combination is provided that comprises a sample suspected of containing the analyte, a chemiluminescent reagent as described above and a sensitizer reagent capable of generating singlet oxygen. The combination is subjected to conditions for binding of the analyte to the binding partner for the analyte. The sensitizer is activated and the amount of luminescence generated by the chemiluminescent composition is detected wherein the amount of luminescence is related to the amount of the analyte in the sample.

    摘要: Methods are disclosed of designing antibodies for a sandwich assay for a small molecule having a molecular weight of about 500 to about 2,000. The method comprises preparing a first antibody that binds to the small molecule, and preparing a second antibody that binds to the small molecule at a portion of the small molecule other than a portion to which the first antibody binds. The second antibody is prepared from an immunogen that comprises a predetermined portion of the small molecule. The antibodies may be employed in sandwich assays for the small molecule.
