Patent number: 7018802Abstract: Electrochemiluminescent-labels and enzyme substrates, which preferably are conjugated, are used in immunoassays and electrochemiluminescence is generated catalytically. In conventional electrochemiluminescence immunoassays, an anti-analyte antibody molecule can give rise to typically 6–8 electrochemiluminescence-active ruthenium atoms, while in the present invention, each enzyme-labeled anti-analyte molecule can give rise to thousands of electrochemiluminescence-active ruthenium atoms per second. An exemplary immunoassay is based on a catalytic process employing ?-lactamase-conjugated anti-analytes which enzymatically hydrolyze electrochemiluminescent-labeled substrates, making them strongly electrochemiluminescent. The electrochemiluminescence signal generated by each anti-analyte molecule (i.e., each analyte molecule) is much greater than with the conventional method. Accordingly, greater sensitivity can be gained in the measurement of low concentrations of a given immunoassay analyte.Type: GrantFiled: September 4, 2002Date of Patent: March 28, 2006Assignee: BioVeris CorporationInventors: Mark T.

Patent number: 6872828Abstract: 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.Type: GrantFiled: December 20, 2001Date of Patent: March 29, 2005Assignee: Lumigen, Inc.Inventors: Hashem Akhavan-Tafti, Renuka de Silva, Wenhua Xie
