Tandem mass spectrometry is a powerful tool in proteomics. By ionizing peptides and then fragmenting those ions into smaller product ions, researchers can determine the biomolecules’ amino acid ...

Effective protein characterization depends on the precise isolation and fragmentation of peptide ions within the mass spectrometer, typically coupled with liquid chromatography (LC-MS/MS). In a ...

TOF-SIMS is a mass spectrometry technique in which a solid sample is bombarded by ions, which then release fragments of the surface molecules. The material ejected from the sample typically is from ...

In this Teach Me in 10, Dr. Amanda Lee, Product Marketing Manager at Thermo Fisher Scientific, explains how optimizing mass ...

Sensitivity is a fundamental performance characteristic of a mass spectrometer. Increasingly higher sensitivities are in constant demand in order to characterize and quantify analytes that are at an ...

An algorithm designed by researchers from Carnegie Mellon University's Computational Biology Department and St. Petersburg State University in Russia could help scientists identify unknown molecules.

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 ...

BALTIMORE--(BUSINESS WIRE)-- For the 73rd Conference on Mass Spectrometry and Allied Topics (ASMS), Bruker Corporation (Nasdaq: BRKR) announced the launch of the timsOmni™ system, a transformative new ...

Methylation (namely addition of a methyl group) of arginine amino acid residues of proteins is a post-translational modification (PTM) catalyzed by a family of nine enzymes called Protein Arginine ...
