The emergence of proteomics, the large-scale analysis of proteins, has been inspired by the realization that the final product of a gene is inherently more complex and closer to function than the gene itself. Shortfalls in the ability of bioinformatics to predict both the existence and function of genes have also illustrated the need for protein analysis. Moreover, only through the study of proteins can posttranslational modifications be determined, which can profoundly affect protein function. Proteomics has been enabled by the accumulation of both DNA and protein sequence databases, improvements in mass spectrometry, and the development of computer algorithms for database searching

e-MSion helping scientists across the globe by leveraging the e-MSion ECD-EMS solutions in a number of key areas, including:

Monitor enzyme reactions, confirm amino acid sequences, and identify large proteins from databases that include samples derived from proteolytic fragments.
Monitor protein folding, carried out by means of hydrogen-deuterium exchange studies, and important protein- ligand complex formation under physiological conditions.
Help in the challenges of systems biology and functional genomics is to integrate proteomic, transcriptomic, and metabolomic information to provide a better understanding of cellular biology.

The life sciences and pharmaceutical industry is dedicated to improving quality of life by developing innovative therapies and medicines that promise longer, healthier and more active lives.
