  • Soluble analyte detection and amplification
    Patent number: 9181579
    Abstract: The present invention relates to a method of detection of a compound of interest that is present at low levels in a sample. In particular, the present invention relates to a method of detection of a compound of interest in solution by a nucleic acid-labelled binding construct, separation of the unbound nucleic acid-labelled binding construct, and the detection of the bound nucleic acid-labelled binding construct in the solution phase. The present invention is particularly adaptable to be used in conjunction with a nucleic acid amplification reaction for detecting the presence or absence of the nucleic acid portion of binding construct in a sample indicating the presence or absence of the compound of interest.
    Type: Grant

  • Canine allergy therapeutic recombinant chimeric anti-IgE monoclonal antibody
    Patent number: 6504013
    Abstract: The present invention provides methods and compositions for decreasing IgE levels in dogs. The methods and compositions are useful for treating allergic symptoms in dogs. The invention may comprise chimeric canine anti-IgE monoclonal antibody compositions and methods for using the compositions in the treatment of allergy. In preferred embodiments, the compositions of the present invention may act by binding soluble IgE in plasma, or by inhibiting IgE from binding to receptors on mast cells, B cells, and basophils.
