Abstract: Snake venom is a complex mixture of proteins and peptides which in the Viperidae is mainly hemotoxic. The diversity of these components causes the venom to be an extremely interesting object of study. Discovered components can be used in search for new pharmaceuticals used primarily in the treatment of diseases of the cardiovascular system. In order to determine the protein composition of the southern copperhead venom, we have used high resolution two dimensional electrophoresis and MALDI ToF/ToF MS-based iden… Show more

“…In the 2-D Quant Kit method, copper ions attach to the peptide bonds in the protein, so this method is independent of the amino acid composition of the proteins in the sample. This kit has been repeatedly used to measure the concentration of proteins in venom [28,39] and this is also the most commonly used method in our laboratory [10,34,35,40]. However, obtained results by 2-D Quant Kit and Bradford for A. contortrix venom show low variability, whereas for N. ashei venom, the differences are large.…”

“…However, obtained results by 2-D Quant Kit and Bradford for A. contortrix venom show low variability, whereas for N. ashei venom, the differences are large. This observation could explain why we have never managed to obtain well-separated and optimized gels for species of the genus Naja [40] and Dendroaspis, and we have had no problems with Viperids [10,34]. As the gel staining procedure involves the use of Coomassie Brillant Blue, which is also the dye in the Bradford method, the significant difference in the concentration values obtained from Bradford and 2-D Quant kit assays in the case of Naja ashei may be the reason why we observed gels that were not stained enough as if we added too few proteins.…”

“…Generally, svPLA 2 s are among the main protein components of snake venoms (Bernardes et al, ; Boldrini‐Franca et al, ; de Oliveira et al, ). Proteomic and functional studies on snake venoms from Agkistrodon contortrix contortrix (Bocian et al, ) , Micrurus lemniscatus (Casais et al, ), and Agkistrodon piscivorus leucostoma (Lomonte et al, ) have revealed that PLA 2 s are the major component of these venom proteomes. In certain species of snakes, such as Bungarus multicinctus , svPLA 2 s correspond to up 60% of the proteome, covering different isoforms (Bocian et al, ).…”
