Figure 3. Peptide mixture MS data analysis by Skyline software. Chromatograms of the peptide ions for sequences uploaded in Skyline as the FASTA format (А). An example of the peptide (LNDTTLQVLNTWYTK) ion m/z = 905.4727 chromatogram (B). Dependence of m/z = 905.4727 fragment ions intensities on retention time. The figure shows that not all fragments are co-eluted (C), so they should be excluded from the further analysis. Distribution of relative intensities of fragment ions of peptide precursor ion m/z = 905.4727 (D).
