The Lethal Toxin Neutralizing Factor, or LTNF, is a protein found in the blood serum of opossum. The North American Opossum (Didelphis virginiana) is notable for its ability to live through snake bites.[1] The protein could potentially be used to treat most snake bites as it is capable of neutralizing the venom of major snake families.[2] Furthermore, most modern antivenoms come from horse proteins to which many people are allergic. The molecular weight of LTNF is about 63 kDa.[2]
