FIG. 1.

Western blot analysis of reactivity of P66-specific monoclonal antibodies against protease-treated B. burgdorferi B31. Spirochetes were treated with buffer alone (N), trypsin (T), or proteinase K (P). After PAGE and transfer to membrane, the cell components were reacted with murine monoclonal antibody H914 or H1337. Molecular weight standards (MWS) in thousands are shown to the left.
