    The effects of a goat anti-guinea-pig beta 2-microglobulin antiserum (a beta 2m) on lymphocyte transformation, induced by specific antigens or mitogens, were studied. a beta 2m was found to exert inhibitory effects on antigen stimulation, with three different antigens (purified protein devivative, hen egg-white lysozyme, and ovalbumin), and on stimulation induced by the 'T-cell mitogens', concanavalin A and phytohaemagglutinin, and the 'mixed mitogen', pokeweed mitogen. Stimulation induced by the 'B-cell mitogens', dextran sulphate and bacterial lipopolysaccharide, did not seem to be inhibited to the same extent by a beta 2m. The inhibitory effects seemed specific, as they were not seen with a beta 2m that had been absorbed on a column with insolubilized purified guinea-pig beta 2m nor with normal goat serum. Time studies indicated that the inhibitions started already during the first day of culture.

    Hybridoma Technology

    Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or epitope. Such antibodies are used in research, diagnostics, and disease therapy. The hybridoma technology established in 1975 by Georges Köhler and Cesar Milstein was awarded the Nobel Prize in Medicine in 1984 for revolutionizing research and therapy.
