Immunodepletion of venom proteins from Bitis taxa by the polyspecific EchiTAb-Plus-ICP antivenom. Panels B, D, F, H, and J show, respectively, reverse-phase separations of the proteins recovered after incubation of the crude venoms of (A) B. arietans (from Ghana), (C) B. arietans (Nigeria), (E) B. nasicornis, (G) B. rhinoceros, and (I) B. gabonica gabonica with the polyspecific EchiTAb-Plus-ICP antivenom, followed by rabbit anti-horse IgG antiserum and immunoprecipitation. The inset shows SDS-PAGE analyses of β-mercaptoethanol-reduced fractions labeled as in the respective chromatograms. Protein fraction numbering is as in Table 1.
