title: Biochemical properties of Egyptian Cerastes venoms in relation to geographic distribution.
abstract: Total proteins, electrophoretic analysis, biological lethality, and phospholipase activity of five members of the Cerastes-viper species living along the Nile Valley were investigated. Elevation of environmental temperature was accompanied with high values for these indices. It is concluded that zoological distribution and environmental conditions could influence the overall biological behaviour of snake venoms of the same species.
