Classification of snake venoms using Raman spectroscopy
Snake venoms are complex, predominantly protein, mixtures. To assess the composition of snake venoms, a team of scientists from IBCh RAS and GPI RAS proposed a method based on Raman spectroscopy, which does not require sample preparation, and the necessary amount of samples is extremely small. Raman spectrum of a protein contains unique information about its primary and secondary structures. Authors conducted a study of dry venoms of various snake species from different genera and families. On the basis of the spectra, with the help of mathematical methods, a classification of venoms was carried out, reflecting their composition and the assignment of a producing snake to the corresponding family or even genus. The method can be used to analyze composition and variations of venoms. The results are published in Journal of Materials Chemistry B. Learn more
