Additional file 5. Figure S4 Sample MS and MS/MS spectra. MS spectra corresponding to the heavy- and light-labeled peptide LIFAGK from the ubiquitin-60S ribosomal protein L40 (sp|P62987|RL40_HUMAN) are shown. Relative peak intensities of all heavy- and light-labeled detected peptides are used to estimate relative quantitation of parent proteins. The MS/MS spectra of the LIFAGK peptide show the daughter b- and y-ions generated by collision with the neutral gas helium; these ions are used to confirm the peptide sequence.
