  • Reagents for reducing leukocyte interference in immunoassays
    Patent number: 9316638
    Abstract: Methods and devices for reducing interference from leukocytes in an analyte immunoassay are provided. In one embodiment, a method is provided comprising the steps of amending a biological sample such as a whole blood sample with one or more leukocidal reagents that reduce or eliminate the metabolic activity of leukocytes, and performing an immunoassay on the amended sample to determine the concentration of analyte in the sample. Preferably, the sample is amended with one or more enzymes and optionally one or more enzyme substrates and cofactors.
    Type: Grant
    Filed: March 30, 2015
    Date of Patent: April 19, 2016
    Assignee: Abbott Point of Care, Inc.
    Inventors: John Lewis Emerson Campbell, Graham Davis, John Emegbero Omakor, Adam Roger Moss, Ganesh Guhados
  • Nanosilver coated bacterial cellulose
    Patent number: 9200086
    Abstract: Nanosilver coated bacterial cellulose nanofiber and a method of producing the nanosilver coated bacterial cellulose nanofiber. The nanosilver coated bacterial cellulose nanofiber is produced by preparing a suspension of bacterial cellulose fibers, oxidizing bacterial cellulose fibers; adding the thio-group to the polymer backbone; reacting the resulting product with silver proteinate and enhancing the nanosilver particle size. The nanosilver coated bacterial cellulose nanofibers exhibit antimicrobial properties.
