Abstract:
The invention relates to methods for conducting solid-phase binding assays. One example is an assay method having improved analyte specificity where specificity is limited by the presence of non-specific binding interactions.
Abstract:
Luminescence test measurements are conducted using an assay module having integrated electrodes with a reader apparatus adapted to receive assay modules, induce luminescence, preferably electrode induced luminescence, in the wells or assay regions of the assay modules and measure the induced luminescence.
Abstract:
The present invention relates to methods, compositions, compounds and kits for detecting, measuring and modulating protein ubiquitylation via the N-end rule pathway and for identifying novel substrates, enzymes and modulators of N-end rule ubiquitylation. The present invention also relates to specific substrates of N-end rule ubiquitylation as well as activated fragments of these substrates, proteases that expose N-degrons in these substrates, ubiquitin ligases that ubiquitylate these substrates and inhibitors of the ubiquitylation of these substrates.
Abstract:
A method and apparatus for performing electrochemiluminescence assays are presented. In exemplary embodiments of the present invention an apparatus comprises an ECL-inactive electrode surface having a first assay-ligand immobilized thereon and an ECL-active microparticle having a second assay ligand immobilized thereon. In exemplary embodiments of the present invention a method comprises (a) forming a mixture comprising an electrochemiluminescent label and a microparticle having a first assay-ligand immobilized thereon, (b) applying electrochemical energy to an electrode surface in the presence of said mixture, and (c) measuring emitted electrochemiluminescence, where the microparticle is ECL-active and where the electrode surface is ECL-inactive when electrochemical energy is applied to it in the presence of said mixture.

Abstract:
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.
