Abstract
Methods are disclosed for a sandwich assay for a small molecule having a molecular weight of about 500 to about 2,500. The method comprises the use of a first antibody that binds to the small molecule and 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 hapten that is not the small molecule or a derivative of the small molecule wherein the hapten comprises a moiety that is structurally similar to that of the second portion of the small molecule. The antibodies may be employed in sandwich assays for the small molecule.
