Proteomics is the study of all proteins in a biological system (e.g., cells, tissue, organism) during specific biological events (1, 2). Although complementing genomics, proteomics is considerably more difficult to study than genomics or even transcriptomics because of the dynamic nature of proteins expression. Additionally, the majority of proteins undergo some form of post-translational modification (PTM), which further increases the proteomic complexity. The broad scope of proteomics has only begun to be realized within the last 15 years due in large part to technological developments in mass spectrometry.
