Workflow for cross-linking mass spectrometry relies heavily on effective ion activation methods for the production of informative MS/MS spectra. After optimized incubation of proteins with a cross-linking reagent and proteolytic digestion, four types of peptide products may be created. Cross-linked peptides are subjected to ion activation to generate informative MS/MS spectra.190 Reprinted from Götze, M.; Iacobucci, C.; Ihling, C.H.; Sinz, A.
