Fragment ions calculated from the identified peptide are shown in the MS 2 (first fragmentation) and MS 3 (second fragmentation) mass spectra. The highlighted residue is the position of the SNP.

Many software packages allow one to effectively interpret collision cell fragmentation mass spectra (high resolution), but such mass spectra differ significantly from EI-MS mass spectra, mainly in ...

Surface melting on the Greenland Ice Sheet is on a slightly above-average track for the 2025 melt season, with melt along the western coast leading the way. Overall, total melt-day extent as of June ...

Fragmentation of intact proteins in the gas phase is influenced by amino acid composition, the mass and charge of precursor ions, higher order structure, and the dissociation technique used. The ...

Non-targeted analysis (NTA), including both suspect screening analysis (SSA) and unknown compound analysis, has gained increasing popularity in various fields for its capability in identifying new ...
