Figure 1. Binding of anti-capsular antibodies to PGA-coated sensor surface. The total RU that was achieved following a 180 sec pulse is given as a function of antibody concentration. The KD of each antibody was determined using the steady-state equilibrium model in BIAevaluation software, where the theoretical RUmax is determined and the apparent KD is equal to the antibody concentration that is necessary to reach ½ RUmax.
