Specific and competitive binding of IgG1, IgG2a, and IgG2b mAbs to PA. (A) IgG1, IgG2a, and IgG2b mAbs were added at different concentrations to PA bound to polystyrene plates. Binding was measured by ELISA. (B) A constant amount of IgG1 (2 µg/ml) and increasing concentrations of IgG2a and IgG2b were allowed to compete for binding to PA bound to polystyrene plates. Data shown are representative of three independent experiments.
