Figure 1. The distribution of peptides in serial dilutions obtained in [3] and data combined into a virtual pulled set. Ramos et al. - data from [3]. Sample identification: peptides identified for a particular dilution were used. All identifications: all the peptides identified in [3] were used, regardless of dilution. Selected: additional filtration (accuracy of primary ions comparison was 5 ppm, peptides with N-terminal acetylation was removed).
