Figure 2

Quality assessment of label-free quantitative mass spectrometry data acquisition. (A) Scatter plot of peak intensities between the technical replicates of the salivary proteome of visit V1, V2, and V3, the Pearson correlation coefficient is indicated at the bottom of each plot. (B) The left side panel shows boxplots of precursor responses before normalization for each run at V1, V2, and V3 with technical repeats. Similarly, the right-side panel shows boxplots of the same precursor responses after normalization based on the median of total ion current (TIC). (C) Reproducibility of identification of the average precursors (green columns) and protein groups (pink columns) within the visit and technical repeats in all analyzed 20 saliva samples. Data represents mean ± SE of 20 independent data for each run at V1, V2, and V3 with technical repeats. (D) The dot plot shows the %CV distribution for all conditions, V1, V2, and V3. Data represent mean with SD of 20 independent data for each run at V1, V2, and V3.
