(RSS) (BioRxiv All) In-source fragmentation in mass spectrometry-based proteomics: prevalence, impact, and strategies for mitigation: Peptide-level analyses are becoming increasingly popular in mass spectrometry-based proteomics and are being applied, for example, in immunopeptidomics, structural proteomics, and analyses of post-translational modifications. In such analyses, peptides that are not biologically meaningful but instead arise as… https://www.biorxiv.org/content/10.64898/2026.03.27.714398v1?rss=1&utm_source=dlvr.it&utm_medium=mastodon #BioRxiv #MassSpecRSS
