  • Detection of nicotine metabolites
    Patent number: 8785205
    Abstract: The present invention relates to assays for detection of nicotine metabolites, in particular cotinine, in fluid samples and uses of these assays in quantification of smoking habits. The assays comprise contacting a body fluid sample with a cyanogen halide and a pyrazolone compound and detecting a change in light absorbance of the pyrazolone compound which is associated with the presence of nicotine metabolites. Also provided are assay kits including a cyanogen halide or cyanogen halide-precursor(s) and a pyrazolone compound.
    Type: Grant
    Filed: May 13, 2011
    Date of Patent: July 22, 2014
    Assignee: GFC Diagnostics Ltd.
    Inventors: Charles John Knill, John Frederick Kennedy

  • Reactive matrices
    Patent number: 4070246
    Abstract: Compositions comprising stable, water-insoluble coatings on substrates to which biologically active proteins can be covalently coupled so that the resultant product has the biological properties of the protein and the mechanical properties of the substrate, for example, magnetic properties of a metal support. The resultant product can be utilized in diagnostic immunoassays as an example, and when the metal substrate is magnetic, the product can be removed from liquid media by a magnetic field ensuring that any washing or incubation process can be finished promptly and efficiently.
