Production and Partial Characterization of Mouse Monoclonal Antibodies Recognizing Common Cytokine Receptor Gamma Chain (gammac) of Human, Mouse and Primate Origin

Monoclonal antibodies specific for the common cytokine receptor gamma chain, gammac, were produced using traditional hybridoma technology. Fusion of P3X63-Ag8.653 myeloma cells with splenocytes from Balb/c mice immunized with Spodoptera frugiperda insect cells infected with the recombinant baculovirus VL1392-hIL-2Rgamma resulted in several hybridoma cell clones producing monoclonal gammac-specific antibodies. Four of these antibody-producing clones, IIIC3, IIIE8, IG3 and IF10C5, were further characterized by immunoblotting, flow cytometry and ELISA. Data are presented demonstrating that the generated monoclonal antibodies can identify the extracellular domain of the common cytokine receptor gamma chain of human and mouse origin, and two of the antibodies recognize gammac of primate origin as well.
