The preparation and properties of monoclonal antibodies against carbohydrate-binding proteins (discoidin I and discoidin II) in the cellular slime mold, Dictyostelium discoideum are described. Monoclonal antibody (mAb) ndI, II-1 bound both discoidins I and II specifically. mAb nl-1 and mAb dl-1 bound only discoidin I but their binding specificities were different: nl-1 recognized the native form and dl-1 the denatured form. mAb dll-1 bound only denatured discoidin II. In preliminary work mAbs dII-1 and nl-1 were found to be useful for localizing discoidins I and II immunohistochemically.
