The venom of the scorpion Tityus costatus contains peptides toxic to humans but scarce information on their structure and function is available. Here, we report the separation of 50 different components by high performance liquid chromatography and the identification of approximately 90 distinct components by mass spectrometry analysis, with molecular weights varying from 413 to 45482 atomic mass...
The investigation of venoms has many clinical, pharmacological, ecological and evolutionary outcomes. The Crotalus spp. venom can cause hemorrhage, neurotoxicity, myotoxicity, coagulopathy and hypotension. Although neurotoxicity and hemorrhage usually does not occur for the same species, the rare Venezuelan species Crotalus vegrandis presents both characteristic. Different from the other species it...
The application of proteomic tools to the study of snake venoms has led to an impressive growth in the knowledge about their composition (venomics), immunogenicity (antivenomics), and toxicity (toxicovenomics). About one-third of all venomic studies have focused on elapid species, especially those of the Old World. The New World elapids, represented by coral snakes, have been less studied. In recent...
