Summary for Patent: 6,056,957
Title: Humanized monoclonal antibodies against human interleukin-5
Abstract:A monoclonal antibody is provided which specifically binds to human interleukin-5. Also provided are a hybridoma which produces the monoclonal antibody; complementary DNAs which encode the heavy and light chain variable regions of the monoclonal antibody and CDRs therefrom; humanized monoclonal antibodies; and pharmaceutical compositions comprising the monoclonal antibody or anti-idiotypic antibodies directed against it, humanized monoclonal antibodies, binding fragments, binding compositions or single-chain binding proteins derived from the antibody and a physiologically acceptable carrier.
