Supplementary Figure 2: Charge state distribution of unlabeled and EASI-tag-labeled peptides.
From: EASI-tag enables accurate multiplexed and interference-free MS2-based proteome quantification

Distribution of charge states for all features detected by MaxQuant for unlabeled HeLa peptides and EASI-tag-labeled peptides from the one and two proteome experiments for (N=9 for unlabeled and N=3 for EASI-tag-labeled). The center bars indicate the mean values.
