WebRecently the combination of bottom-up and top-down proteomics, so called middle-down proteomics, is receiving a lot of attention as this approach not only can be applied to the analysis of large protein fragments but also avoids redundant peptide sequences. See also. Protein mass spectrometry; Shotgun proteomics; Top-down proteomics WebMass spectrometry (MS) has emerged over the last two decades as the analytical technique of choice in systems-level protein studies, known as proteomics. Two are the MS-based approaches generally applied to proteomics: bottom-up (BU), which relies on the proteolytic digestion of proteins into short (~10 amino acids) peptides, and top-down …
