sds gel electrophoresis and western blotting of ricin-binding proteins purified from rod outer segment membranes by lectin affinity chromatography revealed the existence of two major polypeptides of mr 215k and 103k , the former of which was found to specifically react with pme 1b3 , a monoclonal antibody specific for the 230-kda non-neuraminidase-treated na+/ca2+ exchanger .
