A process for recovering thrombin-like enzymes from snake venoms, or snake venom fractions

摘要

A process for the preparation of thrombin-like proteolytic enzymes from snake venoms or fractions thereof comprising contacting the snake venom or fraction thereof with heparin insolubilized by reaction with a water-insoluble carrier in order to bind the thrombin-like enzyme to the insolubilized heparin, removing the undesirable accompanying substances of the snake venom and splitting the thrombin-like enzyme from the insolubilized heparin.
