Fig. 2. (a) Mass spectrum of peptide showing multiply protonated ions of the analyte. Note that not the first (monoisotopic) signals are annotated, but the most abundant one where 13C is incorporated. (b) MS/MS spectrum of peptide QELCTWERGSVRQADK (LysC digest, coverage from doubly protonated spectrum in top of list, from triply protonated ion in bottom of list). (c). MS/MS spectrum profile of a) peptide TSKQELCTWER (tryptic digest), b) peptide GSVRQADKTLAG (tryptic digest), c) peptide GRTSKQELCTWER (tryptic digest).
