Protein Mass Spectrometry

Protein Mass Spectrometry (MS) is a powerful analytical technique used to measure the mass-to-charge ratio and abundance of proteins or peptides. It is used to identify and characterize proteins, including those within complex mixtures. By allowing quantitative, label-free and highly precise measures of protein expression, it is used in a number of research fields, including proteomics and drug discovery. It has also become a vital tool in identifying and profiling post-translational modifications, and in studying protein-protein interactions. MS has become a critical technique for clinical diagnostics and biomarker discovery in clinical research.
