  • Immunoassay for breast cancer employing monoclonal antibodies
    Patent number: 4707438
    Abstract: An immunoassay for diagnosing and monitoring human breast cancer. The assay employs a monoclonal antibody which recognizes a human mammary tumor virus derived from the T47D clone-10 breast cancer cell line (HMTV). The monoclonal antibody is produced by the hybridoma cell line deposited with the American Type Culture Collection under ATCC Accession No. HB 8630.When the immunoassay is performed on a tissue sample from a subject, the sample is contacted with monoclonal antibody ATCC Accession No. HB 8630 so as to form an antibody-antigen complex between the monoclonal antibody and any HMTV antigens which may be present in the sample. This antibody-antigen complex is then detected employing a second detectable antibody specific to the first monoclonal antibody. The presence or absence of the complex indicates the presence or absence of breast cancer in the subject.
