Thiruvananthapuram: A chicken egg could well be the answer to a snake-bite with the scientists at the Sree Chitra Tirunal Institute for Medical Sciences and Technology here developing a highly purified viper antivenom from chicken eggs. With the biochemical and preliminary animal studies having been successfully completed, the product is all set for human clinical trials. Six-month old egg-laying Rhode Island Red hens were injected with viper venom and the anti-venom from the hen gets concentrated in the egg. The eggs collected from the 12th day to the 90th day give a good yield of anti-venom.
