Abstract: Acridans which are reactable with a peroxidase and peroxide. The acridans are characterized by having an aromatic leaving group ArO which is a di- or polyhalosubstituted phenoxy group. The compounds are useful in assays where one member of a binding pair is linked to the peroxidase and for detecting the peroxidase. The method can also be used to detect hydrogen peroxide.

Abstract: Polymeric phosphonium salts useful for enhancing the chemiluminescence produced by 1,2-dioxetanes are described. The polymers are preferably water soluble and used in immunoassays and nucleic acid assays with enzyme triggerable 1,2-dioxetanes.

Abstract: A chemiluminescent assay method and compositions are described which use a dialkyl-substituted dioxetane which is deprotected to trigger a chemiluminescent reaction. Chemiluminescent 1,2-dioxetane compounds substituted on the dioxetane ring with two nonspirofused alkyl groups which can be triggered by a reagent to generate light are disclosed. Dialkyl-substituted dioxetanes are useful for the detection of triggering agents including enzymes. The enzyme may be present alone or linked to a member of a specific binding pair in an immunoassay, DNA probe assay or other assay where the enzyme is bound to a reporter molecule.

Abstract: An assay method, compositions and test kits using a hydroxyaryl cyclic diacylhydrazide is described. A hydrogen peroxide and peroxidase enzyme. The preferred compositions incorporate enhancer compounds and a chelating agent which suppresses light production prior to addition of a peroxidase enzyme. The assay method can test for a peroxidase enzyme, a peroxide or can be used in immunoassays and probe assays.

Abstract: Aryl N-alkylacridanthiocarboxylate compounds which produce chemiluminescence. The compounds produce light with peroxide and peroxidase. The compounds are used as a substrate in assays for various analytes.

Abstract: N-alkylacridan carboxylic acid derivative compounds (I) are used to generate chemiluminescence by the action of a peroxidase enzyme and an oxidant. The compounds I are useful in assays of all types.

Abstract: A dicationic surfactant for enhancing the chemiluminescence of chemiluminescent compounds particularly dioxetanes which are triggerable is described. The surfactant has the formulaX.sup.- (R.sub.1).sub.3 A.sup.+ CH.sub.2 --Link--CH.sub.2 A.sup.+ (R.sub.2).sub.3 X.sup.-wherein A is selected from the group consisting of phosphorus and nitrogen atoms separately or together, wherein X is an anionic counterion and R.sub.1 and R.sub.2 are selected from the group consisting of unsubstituted and substituted alkyl and aralkyl groups containing 1 to 20 carbon atoms and R.sub.1 and R.sub.2 can be the same or different, and wherein Link is a carbon chain group selected from the group consisting of dialkylenearyl, aryl, alkylene, alkenylene and alkynylene groups containing 4 to 20 carbon atoms. The surfactants are particularly useful in Western and Southern blot assays.

Abstract: Triggerable dioxetanes with a fluorescent molecule containing group bonded or tethered in the dioxetane so as to produce fluorescence from the group are described. The compounds are useful in immunoassays and in probes using enzymes or other chemicals for triggering the dioxetanes to produce light from the fluorescent molecule in the group as a signal.
