Reverse-phase separations of the venom proteins (upper chromatograms) from C. tigris (A), C. horridus (B), C. oreganus helleri (C), C. scutulatus scutulatus (type A) (D), and S. catenatus catenatus (E), and the toxins recovered after incubation of the crude venoms with the experimental trivalent antivenom against C. simus, C. l. lepidus, C. d. terrificus (lower chromatograms), followed by immunoprecipitation with Agarose-Protein A.
