Abstract: Novel compounds comprising a C—C double bond substituted at one carbon with two sulfur atom-containing groups are disclosed. The compounds are useful in methods and compositions for generating chemiluminescence rapidly by reaction with a peroxidase enzyme and a peroxide. The chemiluminescence thus produced can be used as a detectable signal in assays for peroxidase enzymes or peroxide-producing enzymes and in assays employing enzyme-labeled specific binding pairs.

Abstract: Methods for generating chemiluminescence rapidly by reaction of at least one compound comprising a C—C double bond substituted at one carbon with two sulfur atom-containing groups with a peroxidase enzyme and a peroxide are disclosed. The chemiluminescence thus produced can be used as a detectable signal in assays for peroxidase enzymes or peroxide-producing enzymes and in assays employing enzyme-labeled specific binding pairs. Use of the methods provides rapid signal generation, achieving a plateau intensity in under one minute. The substrate can be provided in a composition which demonstrates unexpectedly long storage stability.

Abstract: Solid phase materials for binding nucleic acids and methods of their use are disclosed. The materials feature a cleavable linker portion which can be cleaved to release bound nucleic acids. The solid phase materials comprise a solid support portion comprising a matrix selected from silica, glass, insoluble synthetic polymers, and insoluble polysaccharides to which is attached a nucleic acid binding portion for attracting and binding nucleic acids, the nucleic acid binding portion (NAB) being linked by a cleavable linker portion to the solid support portion. Preferred nucleic acid binding portions comprise a ternary or quaternary onium group. The materials can be in the form of microparticles, fibers, beads, membranes, test tubes or microwells and can further comprise a magnetic core portion. Methods of binding nucleic acids using the cleavable solid supports are disclosed as are their use in methods of isolating or purifying nucleic acids.

Abstract: Stable, enzymatically triggered chemiluminescent 1,2-dioxetanes with improved water solubility are provided. Dioxetanes further instituted with two or more water-solubilizing groups disposed on the dioxetane structure provide superior performance by eliminating the problem of reagent carryover when used in assays performed on capsule chemistry analytical systems. Compositions comprising a dioxetane with two or more water-solubilizing groups, a non-polymeric cationic surfactant enhancer and optionally a fluorescer, for providing enhanced chemiluminescence are also provided.

Abstract: Improved assay methods utilizing stable, enzymatically triggered chemiluminescent 1,2-dioxetanes with improved water solubility are provided. Assays are performed by a capsule chemistry analytical assay method wherein fluid capsules comprising discrete aqueous segments containing either a chemiluminescent dioxetane reagent or an activating agent separated by an oil-based isolating fluid are flowed through a conduit, and subsequently reacted to produce light.The improvement comprises using a dioxetane substituted with two or more water-solubilizing groups disposed on the dioxetane structure to provide the chemiluminescence. Compositions comprising such a dioxetane, a non-polymeric surfactant enhancer and optionally a fluorescer, provide enhanced chemiluminescence and eliminate the problem of reagent carryover when used in assays performed on capsule chemistry analytical systems.
