this paper describes a new sensitive microelisa based on enzyme/anti-enzyme complexes following an unlabelled antibody bridging step . beta-galactosidase/anti-beta-galactosidase complexes were made using a monoclonal antibody raised against bacterial ( e. coli ) beta-galactosidase and enzyme activity was quantified with a fluorogenic substrate .
