Comparison of the competitive ELISA formats between aptamer–antibody (Apt/Ab) and antibody–antibody (Ab/Ab) sandwich systems. (a,b) Schematic representation of the components in each system, using four DEN-NS1 serotypes. In the Ab/Ab system, the same antibodies for the capture and detection reagents were used.
