title: Development and characterization of monoclonal antibodies to chicken interleukin-15.
abstract: The chicken IL-15 gene was recently cloned and shown to encode a polypeptide with T cell growth factor activity similar to IL-2. To further characterize the chemical and biological properties of chicken IL-15, we generated a panel of monoclonal antibodies against bacterially expressed protein and characterized their binding specificities. All antibodies were reactive by ELISA with recombinant IL-15, but not IL-2, and identified a 15kDa recombinant chicken IL-15 by Western blot analysis. Two antibodies inhibited IL-15-induced proliferation of splenic lymphoblast cells. These monoclonal antibodies will be useful for further structural and immunological studies of chicken IL-15.
