  • ELISA for VEGF
    Patent number: 7541160
    Abstract: The vascular endothelial growth factor (VEGF) activity in a patient's bloodstream or other biological sample can serve as a diagnostic and prognostic index for cancer, diabetes, heart conditions, and other pathologies. Antibody-sandwich ELISA method and kits for VEGF as an antigen were developed to detect VEGF levels in biological samples from animal models and human patients and are used as a diagnostic/prognostic index.
    Type: Grant
    Filed: November 1, 2004
    Date of Patent: June 2, 2009
    Inventors: David Tai Wai Fei, Kristen Tomita

  • Methods for diagnosis of allergy
    Patent number: 5714338
    Abstract: Provided are methods for the diagnosis of allergic disease wherein IgE specific for an allergen of interest is detected in a patient serum sample by using the patient serum sample to sensitize in the presence or absence of an IgE antagonist a mast cell or basophil host genetically engineered to display surface expression of a Fc.epsilon.RI subunit that is capable of mediating the host cells release of a pharmacological mediator upon induction with patient serum and allergen, challenging the sensitized host cells with the allergen of interest, and determining the presence or absence of IgE specific to the allergen of interest in the patient serum sample by comparing the release of the pharmacological mediator produced by host cells sensitized with patient serum in the presence of the IgE antagonist to the release of the pharmacological mediator produced by host cells sensitized with patient serum in the absence of the IgE antagonist.
