Proteomic and biological characterization of the venom of the redtail coral snake, Micrurus mipartitus (Elapidae), from Colombia and Costa Rica

► Venom proteomes of the redtail coral snake, Micrurus mipartitus, from Colombia and Costa Rica were analyzed. ► Three-finger toxins are the predominant proteins in both venoms, followed by phospholipases A2. ► The observed proteomes corroborate the determined in vitro and in vivo activities. ► Four major components of M. mipartitus venom from Colombia were isolated and partially characterized. ► An equine antivenom against Micrurus nigrocinctus fails to recognize M. mipartitus proteins.
