This is a very clear summary of modern knowledge of snake venoms a brief account is given of various fractions of both main types of venom coagulant venoms contain either proteolytic enzymes capable of coagulating pure fibrinogen uninhibited by antithrombin, or enzymes able to convert prothrombin to thrombin. Copperhead venom and cancer research professor frank markland of the university of southern california discusses his research investigating whether contortrostatin, a protein found in copperhead snake venom, is effective in attacking cancer cells and preventing their spread in breast cancer patients. This is similar to the adage that you can potentially eat a snake's venom and not get harmed this is the reason antibody-based drugs are typically injected by avoiding proteolysis of the antibody, it retains its shape and can successfully bind to its epitope.

Snake venoms are complex mixtures of organic and inorganic compounds, many of which display biological activity it has been demonstrated that antisera raised against whole venom or a single purified venom protein from one species of snake will react with proteins in the venom of other species. But as an intriguing new study published in comparative biochemistry and physiology part c: toxicology & pharmacology points out that evolution has had to throw in the towel in its efforts to counter the deadly effects of tiger snake venom new research conducted by associate professor bryan fry from the university of queensland school of biological sciences shows that tiger snake venom hasn’t changed in over 10 million years, and that’s because it hasn’t had to.
