  • Publication number: 20070225498
    Abstract: New chemiluminescent compounds, stable in aqueous buffers, for use in biological assaying include acridanebased compounds and (1,2)-dioxetanes. Among the new acridanebased compounds are water-soluble acridanes, enhancer coupled acridanes, bis and trisacridanes as well as acridane-(1,2)-dioxetanes. Among the new (1,2)-dioxetanes are electron deficient group-containing dioxetanes and tethered bis-1,2-dioxetanes. The (1,2)-dioxetanes are useful as substrates for various enzymes. The acridanes can be admixed with an oxidizing agent. An aqueous buffer and, optionally, a stabilizer to form a substrate or reagent formulation useful for assaying, inter alia, HRP.

  • Publication number: 20050233303
    Abstract: A compound for enhancing the light output of a chemiluminescent system and, in particular, a stabilized, triggerable 1,2-dioxetane, is obtained by reacting a polyvinylbenzyl halide and a bilinker with either a trisubstituted amine or trisubstituted phosphine. A fluorescent molecule may be attached to polymer along with the trisubstituted amine or trisubstituted phosphine. Also, the benzyl halide may be reacted with a ?-electron donor, such as a vinyl naphthalene or vinylanthracene to form a co-polymer which is polymerizable with the trisubstituted amine and/or trisubstituted phosphine. By controlling the reaction parameters it is possible to obtain either a water-soluble or partial water soluble or insoluble compound crosslink polymer.

  • Patent number: 6602679
    Abstract: A substrate having an extended shelf life for chemiluminescent detection and assaying is useful with enzyme-based probes as well as for immunoassays, DNA or RNA or protein detection and blotting. The substrate is a mixture of (a) a chemiluminescent compound, (b) an oxidant, (c) a stabilizer and (d) a buffer. The substrate may further include a chemiluminescent enhancer and a solubilizer. The substrate may be in an organic solvent or may be aqueous based.
