the suggestions for technological advances in this field are : signal amplification using mixtures of monoclonal antibodies directed against different epitopes on the same antigen ( e.g . okt4a+b+d ) , triple layer amplification systems using hapten-labelled antibodies , and informative double staining methods with combinations of antibodies labelled with different fluorochromes or enzymes .
