Lab Study Finds Rattlesnake Proteins Could Reduce Snakebite Mortality

University of Maryland researchers identified toxin-blocking proteins in western diamondback rattlesnakes that neutralize lethal viper venom in lab tests.

University of Maryland researchers identified toxin-blocking proteins evolved in western diamondback rattlesnakes. Laboratory experiments showed optimized protein combinations were 10 times more potent than current sheep-derived antivenom and neutralized lethal effects of rattlesnake venom. The mixtures provided broad cross-species protection against viper venoms, covering species diverged by millions of years of evolution. This work addresses snakebite mortality in regions with limited healthcare access. The findings remain laboratory-scale and have not yet been tested in clinical settings. If validated clinically, this approach could reduce snakebite deaths where existing antivenom is inaccessible due to cost or distribution challenges. What to watch: Clinical trials confirming safety and efficacy in real-world conditions. Current evidence is limited to lab experiments only, with no data on practical deployment requirements or scale-up feasibility.
