In vivo protection of experimentally envenomed mice. A, mice were injected by the subcutaneous route with doses greater than the LD₅₀ of freshly calibrated venom (2 LD₅₀, 3 LD₅₀, or 4 LD₅₀). B, mice were treated after the s.c. injection of 3 LD₅₀ by intraperitoneal injection with PBS-BSA 0.1%, Db4C1op, Db9C2, mixture Db4C1/Db9C2, or mixture Db4C1/Db9C2 injected 5 min after the venom.
