Publication number: 20120055809Abstract: Assay modules, preferably assay cartridges, are described as are reader apparatuses which may be used to control aspects of module operation. The modules preferably comprise a detection chamber with integrated electrodes that may be used for carrying out electrode induced luminescence measurements. Methods are described for immobilizing assay reagents in a controlled fashion on these electrodes and other surfaces. Assay modules and cartridges are also described that have a detection chamber, preferably having integrated electrodes, and other fluidic components which may include sample chambers, waste chambers, conduits, vents, bubble traps, reagent chambers, dry reagent pill zones and the like. In certain preferred embodiments, these modules are adapted to receive and analyze a sample collected on an applicator stick.Type: ApplicationFiled: August 30, 2011Publication date: March 8, 2012Applicant: Meso Scale Technologies, LLCInventors: Eli N.

Patent number: 7052861Abstract: Graphitic nanotubes, which include tubular fullerenes (commonly called “buckytubes”) and fibrils, which are functionalized by chemical substitution, are used as solid supports in electrogenerated chemiluminescence assays. The graphitic nanotubes are chemically modified with functional group biomolecules prior to use in an assay. Association of electrochemiluminescent ruthenium complexes with the functional group biomolecule-modified nanotubes permits detection of molecules including nucleic acids, antigens, enzymes, and enzyme substrates by multiple formats.Type: GrantFiled: December 5, 2001Date of Patent: May 30, 2006Assignee: Meso Scale Technologies, LLC.Inventors: Richard J.

Patent number: 6479233Abstract: Biomolecule analysis using anodic oxidation of aqueous sodium 9,10-diphenylanthracene-2-sulfonate (DPAS) and 1- and 2-thianthrenecarboxylic acid (1-THCOOH and 2-THCOOH) in the presence of tri-n-propylamine (TPrA) as a coreactant in aqueous solution produces electrogenerated chemiluminescence (ECL). In addition, the cathodic reduction of DPAS in the presence of peroxydisulfate (S2O82−) as a coreactant also produces ECL in an acetonitrile (MeCN)-water solution (1:1 by volume). The oxidation of chlorpromazine (CPZ) produces an ECL emission in the absence of an added coreactant following an unprecedented “self-annihilation” mechanism.Type: GrantFiled: May 20, 1998Date of Patent: November 12, 2002Assignee: IGEN International, Inc.Inventors: Allen J. Bard, Thomas Richards, Jonathan K. Leland

Patent number: 6468741Abstract: A labeled substance comprising a biological substance linked to a luminescent rhenium-containing label. Qualitative and quantitative electrochemiluminescent assays using the same. These methods comprise contacting a sample with a reagent labeled with an electrochemiluminescent chemical moiety containing rhenium and capable of combining with the analyte of interest, exposing the resulting sample to chemical, electrochemical, or electromagnetic energy and detecting electromagnetic radiation emitted by the electrochemiluminescent chemical moiety.Type: GrantFiled: September 21, 1998Date of Patent: October 22, 2002Assignee: IGEN International, Inc.Inventors: Richard J.

Patent number: 6136233Abstract: An electrochemiluminescence (ECL)-based assay for the quantitation of classical clinical chemistry analytes, where glucose, ethanol, carbon dioxide, cholesterol, as H.sub.2 O.sub.2 liberating systems coupled to a tris(bipyridyl)ruthenium(II) Ru(bpy).sub.3.sup.2+ luminophore generate an ECL signal, which can be detected spectrophotometrically or electrochemically. The H.sub.2 O.sub.2 present reacts with oxalate in the presence of Ru(bpy).sub.3.sup.2+ to give an ECL response.Type: GrantFiled: August 20, 1998Date of Patent: October 24, 2000Assignee: IGEN International, Inc.Inventors: Fabian Jameison, Jonathan K.
