  • Patent number: 10564159
    Abstract: The present invention provides methods and compositions useful in the diagnosis and management of autoimmune diseases. In particular, the present invention provides improved methods and compositions for the diagnosis and management of Graves' disease. The methods of the present invention not only avoids the need for radioactivity and are much simpler, economical, and rapid than methods traditionally used for the diagnosis of Graves' disease, but also improve upon the sensitivity and detection abilities of previous luciferase-based autoantibody detection assays. Such improvements are based upon the superior performance of assays comprising a chimeric TSH receptor in the presence of a glucocorticoid including, but not limited to, dexamethasone.

  • Patent number: 10088481
    Abstract: The present invention describes a liquid direct fluorescence antibody assay that is rapid and sensitive to detect respiratory virus in infected cells. The assay includes centrifugation of the specimen, incubation of sample and reagents in solution, and detection of the absence or presence of respiratory virus. Sapogenin is used as a detergent to permeabilize the cells for entry of the monoclonal antibodies to react with intracellular antigens. The cells are stained with fluorescently labeled monoclonal antibodies against the viral antigens along with a background stain and a fluorescent nuclear stain. This counter staining decreases background and allows co-localization of antigen and nuclear structures for enhanced detection.

  • Patent number: 9535066
    Abstract: The present invention discloses specific human metapneumovirus monoclonal antibodies. The antibody is at least two-fold less reactive with non-human metapneumoviruses including, but not limited to, respiratory viruses or avian metapneumoviruses. Further, the antibody is at least two-fold more reactive with a human metapneumovirus (i.e., for example, Type A or Type B) than with non-human metapneumoviruses including, but not limited to, respiratory viruses or avian metapneumoviruses. Consequently, these novel antibodies are useful as a clinical diagnostic agent, especially when using fresh nasopharengeal aspirates. The invention also contemplates numerous diagnostic platforms that together with the novel antibodies can support economical, fast, and highly selective detection and identification of clinical inoculum samples.
