Abstract: ABSTRACT           A method for performing a diagnostic immunoassay by solid phase separation for digoxin.  To a reaction mixture of a test sample and labeled anti-digoxin antibody, which forms a complex of any digoxin present in the test sample, is added a solid phase material having an immobilized ouabain triacetate derivative compound capable of binding any excess labeled antibody.  The solid phase material is chosen to rapidly settle whereby a solid and liquid phase is formed.  The liquid phase can then be extracted to measure the amount of digoxin-labeled antibody present therein.  Ouabain triacetate derivative compounds possess sufficient affinity for anti-digoxin antibodies, and are therefore useful in a solid phase separation based digoxin immunoassay for settling out such antibodies without contributing to undesired background interference.  These compounds are also less deleterious to assay performance because of low recognition when leached from the solid phase matrix thereby providing solid phase material with extended shelf life.

Abstract: Water soluble naturally-occurring and synthetic enhancer substances, generally macromolecular in nature, for example globular proteins that include hydrophobic regions such as bovine serum albumin, and polymeric quaternary ammonium salts such as poly(vinylbenzyltrimethylammonium chloride), which have the ability to inhibit light-emitting fluorophores resulting from the decomposition of chemiluminescent compounds from releasing energy through non-light emitting pathways, are disclosed as permitting the stabilization, and hence increasing the light intensity, of such light-emitting fluorophores in aqueous media as compared to the intensity of the light emitted by the same quantities of such fluorophores in aqueous media in the absence of such enhancer substances. Any chemiluminescent chemical compound, including thermally, chemically, electrochemically or enzymatically cleavable 1,2-dioxetanes, for example 3-(2'-spiroadamantane)-4-methoxy-(3"-phosphoryloxy)phenyl-1,2-dioxetane disodium salt, and acridfnium esters, can be used.      Auxiliary fluorophores, for example fluorescein and derivatized fluoresceins, that accept energy from fluorophores produced by decomposition of a chemiluminescent compound and in turn emit detectable energy, can also be present. Such enhancer substance/chemiluminescent compound compositions are useful in detecting the presence or determining the concentration of chemical or biological substances in immunoassays, chemical assays and nucleic acid probe assays, and in chemical/physical probe procedures for studying the microstructures of macromolecules.
