Abstract

UNLABELLED: Treatment of Hypnale hypnale bites with commercial antivenoms, even those raised against its sister taxon Calloselasma rhodostoma, has never been clinically successful. As these two genera have been separated for 20million years, we tested to see whether significant variations in venom had accumulated during this long period of evolutionary divergence, and thus could be responsible for the failure of antivenom. Proteomic analyses of C. rhodostoma and H. hypnale venom were performed using 1D and 2D PAGE as well as 2D-DIGE. C. rhodostoma venom was diverse containing large amounts of Disintegrin, Kallikrein, l-amino acid oxidase, Lectin, phospholipase A2 (acidic, basic and neutral) ..
