Updated project metadata. The venom proteomes of three medically important Nigerian Elapidae snakes Naja haje, Naja katiensis and Naja nigricollis was studied using Hydrophilic Interaction Liquid Chromatography (HILIC) coupled with LC-MS/MS analysis. Peptides/Proteins were identified and characterised using the SEQUEST and X!Tandem algorithms incorporated on to the Scaffold proteome software version 4.10.0. The Nigerian elapid species studied displayed about 70% similarity in composition of their venoms.
