Figure 1

ETD MS/MS spectra. a. Charge reduced precursors (CP) and neutral losses (NL), along with fragment ion peaks are shown for peptide KGsYVGIHSTGFK. The first serine is phosphorylated in this peptide and hence is shown in lower case. b. Precursor peaks and their associated neutral losses are shown here. Removing these intense precursor and neutral loss peaks would aid in improving the sensitivity of sequence search algorithms.
