Essential MGF Quality Control and False Positive Detection Many researchers assume that a high Mascot score automatically means a correct peptide identification. In reality, this is not always true. A Mascot search can produce highly confident results from incorrect precursor information,…

Understanding Fragmentation Logic, Structural Clues, and PTM-Related Neutral Losses in Tandem Mass Spectrometry Neutral loss is one of the most important concepts in LC-MS/MS fragmentation analysis. During CID (Collision-Induced Dissociation) or HC…
Modern LC-MS/MS systems are highly sensitive analytical instruments that depend not only on mass spectrometer performance, but also on stable laboratory environmental conditions. Many users focus primarily on: mass accuracy sensitivity [ Read Sensi…
Modern LC-MS/MS peptide analysis depends not only on mass spectrometer performance, but also on the overall analytical workflow surrounding the instrument. In many real-world proteomics experiments, poor peptide identification is caused not by data…
