Percentage of Ig gene peptide identifications in each sample normalized by the number of known peptide identifications across sample subtypes. This percentile ratio is calculated by dividing the number of known peptide identifications from the total number of Ig peptide identifications within each sample. (ratio = (no. of Ig peptides)/(no. of known peptides) × 100). Different kinds of Ig gene segments are colored. Subtype C (sample groups showing both hypermutation and CIMP characteristics) showed a high number of Ig gene peptide identifications compared to that of other sample subtypes. Chi-squared test of this plot showed p < 0.0001, χ2 = 2927.71.
