Proteomics of venom from Trimeresurus malabaricus

This project mainly aims to characterize the complex toxic components present in the venom of Trimeresurus malabaricus (Malabar pit viper). Since Trimeresurus malabaricus (Malabar pit viper) species are mainly inhabited to plantation crop areas, its envenomation is a serious threat to the human population thriving in these zones, especially to the plantation workers. Therefore, exploring the venom proteome of Malabar pit viper is decisive to develop and design new antivenom and therapeutics against its envenomation. As described in this study, applying various orthogonal separation strategies helped in dissecting venom constituents of Trimeresurus malabaricus and is the first comprehensive attempt in revealing the complex venom profile of Malabar pit viper through proteomics approaches incorporating multiple database searches. In order to achieve this the crude venom components were resolved on a 12% SDS page. Further each of the bands were subjected to in-gel trypsin digestion. The crude venom was also subjected to ion-exchange chromatography separation. The obtained fractions were subjected to in-solution trypsin digestion. All the digested peptides were then subjected to Q-TOF LC-MS/MS analysis.
