Antibody neutralization of a myotoxin from the venom of Bothrops asper (terciopelo)
(1987)Neutralization of biological activities of B. asper myotoxin by a monospecific anti-myotoxin rabbit serum and polyvalent antivenom was studied. Both antisera neutralized myotoxic, phospholipase A and lethal activities of ... -
Antibody-dependent enhancement of toxicity of myotoxin II from Bothrops asper
(2024)Improved therapies are needed against snakebite envenoming, which kills and permanently disables thousands of people each year. Recently developed neutralizing monoclonal antibodies against several snake toxins have ... -
Antibody-mediated neutralization and binding-reversal studies on α-neurotoxins from micrurus nigrocinctus nigrocinctus (coral snake) venom
(1996-03)An ELISA based, non-radioactive acetylcholine receptor (AchR) binding assay was used to detect the alpha-neurotoxins present in Micrurus nigrocinctus nigrocinctus venom. Sera from horses hyperimmunized against M. nigrocinctus ... -
