Top-down mass spectrometry offers the ability to sequence intact proteins—post-translational modifications and all—but is not yet a high-throughput method. As the well-established 'bottom-up ...

The ion-trap LC/MS-MS instrument (Agilent XCT Trap) is our tool for confirmation of target compounds and study of fragmentation pathways. It provides MS n analyses and it has been successfully applied ...

Mass spectrometry is an analytical technique that uses an instrument called a mass spectrometer to measure the mass-to-charge ratios of molecular ions. Molecules fragment within the mass ...
