  • Patent number: 8476033
    Abstract: Compositions and methods for diagnosing ovarian cancer in a patient and for identifying patients with an increased likelihood of having ovarian cancer are provided. The compositions include novel monoclonal antibodies, and variants and fragments thereof, that specifically bind to glycodelin. Monoclonal antibodies having the binding characteristics of a glycodelin antibody of the invention and monoclonal antibodies that bind to a glycodelin epitope of a disclosed antibody are further provided. Hybridoma cell lines that produce a glycodelin monoclonal antibody of the invention are also disclosed herein. Kits comprising one or more of the disclosed glycodelin monoclonal antibodies and for practicing the methods of the invention are further provided. Polypeptides comprising the amino acid sequence for a glycodelin epitope of a disclosed monoclonal glycodelin antibody and methods of using these polypeptides in the production of glycodelin antibodies are also encompassed by the present invention.
