Table I.
Reactivity pattern matrix for the panel of eight selected Fabs. The epitope mapping results revealed four different epitopes exist on PA. Fab A8 recognizes a distinct epitope. Fab F1 and G12, F11 and G3, and G11, H2 and 83H2 recognize a similar epitope, respectively. The later three clusters also have epitope overlapping with each other in some extent.
