--- From Brachistosternus ehrenbergii scorpion venom a specific toxin to mice has been isolated. The toxin denominated Be1 was purificated by means of cationic exchange chromatography on CM-Sephadex C-25 column (16 x 1,1 cm) with ammonium acetate buffer 0,05 M at pH 7, and it characterizes to be a basic protein that constitute 8,1 % of venom total protein. Toxin purity was evaluated by electrophoresis in natives conditions, according to Reisfeld-method, and denaturants conditions by the Schägger-and-von Jagow-method, the toxin is a single chain polypeptide of 6,3 kDa has been determined. The toxin to be inoculated on albino mice; intraperitoneal way (62 mg of Be1) produces some local signals as salival hipersecretion followed by respiratory affection, drags hind feet until death. Intramuscular way (7,6 mg) produces temporal paralysis of the inoculated limb. The toxin has neither phospholipase, nor protease, nor acetylcholinesterase nor acetylcholinesterase inhibitor activity.
