RESUMO
Polyacrylamide gel electrophoresis (PAGE) for basic proteins may be a useful toll for the characterization of whole snake venoms and for the taxonomic classification of snakes of the Elapidae and Viperidae families. However, due to the close proximity of PAGE was not able to provide an efficient differentiation. This article reports the electrophoretic analysis of several venoms from the genera Micrurus, Bothrops, Bothriopsis, Crotalus and Lachesis and shows a typical and distinctive electrophoretic profile for each species, with intraspecific and geographic variation. Even in cases in which extreme morphological similarities were present, such as between B. jararacussu and B. pirajai ("Bahia jararacussu"), differentiation could be evidenced by PAGE. This simple and sensitive procedure may be applied to similar cases involving basic toxins.
