  • Methods for producing human lymphocytes and human monoclonal antibodies, and human monoclonal antibodies produced thereby
    Patent number: 5681729
    Abstract: A method for isolating a human lymphocyte producing an antibody specific to a desired antigen, a method for isolating a monoclonal antibody, as well as monoclonal antibodies produced by the method, are described. The present invention provides a method for isolating a human lymphocyte producing an antibody comprising, in the order mentioned, the steps of: transplanting human lymphocytes into an immunodeficient animal so that the human lymphocytes take in the animal body; immunizing the animal with a desired antigen so as to generate human lymphocytes producing an antibody specific to the antigen; recovering lymphocytes producing antibody by incubating with anti-mouse antibody; and separating human lymphocytes from mouse by centrifugation.
