the co-operative effect could be demonstrated by the formation of binary complexes ( ag : ab , 1:2 ) detected by high-performance liquid chromatography ( hplc ) and by the increase of radioactivity found when the synergistic mab were added to 125i-hgh incubated with mab 4d11 immobilized on polyvinyl microplates .
