Project description:In order to study the proteome of Echis carinatus carinatus venom of Indian origin, crude venom was fractionated on a Shodex KW-803 gel filtration column coupled to Dionex Ultimate 3000 UHPLC system. The resulting peaks were pooled and subjected to in-solution trypsin digestion and subsequent tandem mass spectrometry analysis. The raw data were then analysed using PEAKS 8.5 software to finally decipher the complex venom proteome.
Project description:In India, venom research has largely focussed on the ‘big four’ snakes that are greatly responsible for the burden of snakebite in the Indian subcontinent. This study aims to advance understanding of saw-scaled viper venoms from India, we implemented a multi-faceted approach. We sequenced the venom gland transcriptome of E. carinatus for the first time, while also characterising its venom proteome. This was followed by the evaluation of the biochemical activities of the major toxins in E. carinatus venoms. Finally, we assessed the in vitro binding efficacy and in vivo neutralising potency of commercial antivenoms against E. carinatus
Project description:we used a combination of bottom-up (BU) and top-down (TD) proteomics approaches to identify and characterize venom protein compositions of Echis carinatus sochureki (ECS) from three different Iranian populations.
