Analysis of the HLA-B*40:02-associated ligandome.
A, length distribution of the ligands identified from the peptide pool bound to B*40:02. B, molecular weight distribution of the same set of peptides. The mean (± S.D.) molecular weight of the identified peptides is shown. C, Venn diagram showing the number of sequences identified in the flow-through (continuous line), the IMAC (dashed line), and the TiO2 (dotted line) fractions.
