Abstract

Several antihemorrhagic factors isolated from C. atrox serum are glycoproteins with mol. wt ranging from 65,000 to 80,000. The antihemorrhagic activity of these factors was stable at a pH range of 1.3-11.5 and at temperatures up to 85°C, for 30 min. The isolated antihemorrhagins also neutralized the proteolytic activity of C. atrox venom, as tested with azocollagen and gelatin, and formed a complex with hemorrhagic toxin e isolated from the same venom. The neutralization capacity of the isolated antihemorrhagins was six times as high as the commercial polyvalent antivenom produced for clinical use.
