VELASQUEZ, Luz  and  ESCOBAR, Enrique. Purification and partial characterization of a toxin (Hm3) from Hadruroides mauryi (Francke y Soleglad, 1980) (Scorpiones, Iuridae) venom. Rev. peru biol. [online]. 2004, vol.11, n.2, pp.153-160. ISSN 1727-9933.

A toxin (Hm3) was purified from the scorpion venom Hadruroides mauryi, by ion-exchange chromatography on CM-Sephadex C-25 with 0,05M ammonium acetate buffer pH 7. The toxin produce contraction and immobilize the inoculated limb of white mice, and is a basic protein with a molecular weight of 4,5 kDa. After of 45 minutes inoculated in gastrocnemius muscle of white mice, Hm3 (30,4 mg) increases the plasmatic level of creatine kinase from 252,6 UI/L to 3779,3 UI/L and lactate deshidrogenase from 142,7 UI/L to 248,2 UI/L; likewise increases the level of intramuscular calcium from 34,1 nmoles to 69,3 nmoles. This toxin have not proteolitic or phospholipase activity.

Keywords : Toxin; Hadruroides mauryi; scorpion; scorpion venom.
