Using a combination of chemical modifications, enrichment methods, and mass spectrometry, we can produce a map of the “N-Terminome” of a sample.
Many precursor proteins must undergo post-translational modifications to become biologically active. For example, the majority of peptide hormones are produced as pro-hormones that need to be proteolytically cleaved for hormonal activity. Therefore, workflows that enable the identification of the N-Terminal of one or more proteins can become very interesting. Using a combination of chemical modifications, enrichment methods, and mass spectrometry, we can produce a map of the “N-Terminome” of a sample.
The workflow outlined here can be used to study the N-Terminus of pure proteins or to identify variations in the N-Termini of every detectable protein in a sample.
Get the big picture by combining proteomics, lipidomics, and metabolomics data.
Get in-depth profiling of many classes of biologically relevant lipids using our high resolution instruments.
Sample profiling using either untargeted metabolomics or selected panels of targeted metabolites is the best technique.
