  • Human catechol-O-methyltransferase (COMT) assay
    Patent number: 8927225
    Abstract: Disclosed is an assay (method) to quantify the amounts of catecholamine-O-methyltransferase (COMT) protein in samples, such as extracts from cell cultures, body fluids, tissues, and environmental samples. It uses novel agents (anti-NE, COMT-NE, or COMT-epitope-NE) in combination with two previously described agents (anti-COMT and COMT) in a competitive ELISA system to achieve this aim.
    Type: Grant
    Filed: September 8, 2009
    Date of Patent: January 6, 2015
    Assignee: The University of Hong Kong
    Inventors: Shu Leong Ho, Wing Lok Ho, David Boyer Ramsden

  • CYSTEINE DIOXYGENASE POLYMORPHISMS
    Publication number: 20090297475
    Abstract: The invention relates to the detection and identification of polymorphisms in cysteine dioxygenase (CDO) for the use of that diagnosis to identify a propensity in a patient towards rheumatoid arthritis and/or to have side effects with a number of drugs, to nucleic acid and isolated proteins encoding the polymorphisms, to assays for CDO activity and for the identification of compounds affecting CDO activity, and additionally to use of interferon-? optionally in combination with different compounds, to treat rheumatoid arthritis.
