Figure 3: Comparisons of intensities between control and DMD samples. Box plots comparing the distribution of intensities for discriminant peaks. The peaks 40a, 41a and 42a were selected as examples to compare intensities in DMD and controls as they were shown to be discriminant monoisotopic peaks in Table 2a. Peaks 21a,b; 23a,b,c,d; 24a,b,c were selected as examples to show the distribution of integrated intensities of isotopes within a peptide isotopic cluster (b).
