Development of tetravalent antibody–enzyme complexes employing a lactate oxidase and the application to electrochemical immunosensors
Antibody–enzyme complexes (AECs) are ideal for immunosensing. Although AECs using antibody fragments can be produced by bacterial hosts, their low affinity limits their sensing applications. We have improved the affinity of AECs by combining two antibodies using Catcher/Tag systems; however, it requires multiple antibodies and an enzyme production process. In this study, to realize the production
