  • Monoclonal antibody specifically reactive to surface of human prostatic epithelial cells
    Patent number: 5055404
    Abstract: Monoclonal antibodies Pes-1, Pes-2, Pes-3 and Pes-4 which are respectively produced by hybridomas hPro-1.10G (FERM BP-1986), hPro-4.10H (FERM BP-2634), hPro-5.10F and hPro-1.5F specifically bind to the surface of human prostatic epithelial cells. They do not bind to any of many other normal or tumor tissues. The monoclonal antibodies are prepared by immunizing an animal with pieces of epithelial tissue from human prostate as an antigen, fusing antibody-producing cells of the animal with myeloma cells, selecting a hybridoma which produces the antibody, cultivating the hybridoma and recovering the antibody. The monoclonal antibodies have utility for histological examination for metastatic nests in prostatic cancer, preoperative examination in prostatic cancer, diagnosis of prostatic cancer.
