Purification of hemorrhagic SVMPs from venoms of three vipers of Egypt

► Three hemorrhagic SVMPs from the most dangerous Egyptian viper venoms were purified. ► The purified SVMPs possess close biochemical properties. ► Digestion of the BM proteins by the purified SVMPs was much different. ► The purified SVMPs were potentially capable of interfering with the blood coagulation system. ► These studies could be potentially for production of more efficient antisera for management of viper envenomation.
