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 ...

MALDI In-Source Decay (ISD) Mass Spectrometry has emerged as a powerful technique for the rapid characterisation of peptides. By utilising matrix-assisted laser desorption/ionisation, the method ...

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 ...

In mass spectrometry (MS), workflows are being streamlined and analyses are becoming more sophisticated. In short, MS is becoming faster, easier to use, and more functional. This is welcome news for ...

The process of protein identification typically begins with a bottom-up approach, where proteins are enzymatically digested—most commonly with trypsin—into smaller peptides. These peptides are ...

Just how far mass spectrometry—the use of tools measuring the mass-to-charge ratio (m/z) of one or more molecules present in a sample—has progressed over the past century can be seen in a new exhibit ...
