Extended Data Fig. 5: An example of a false positive MHCII-bound HIP.
From: The MHC-II peptidome of pancreatic islets identifies key features of autoimmune peptides
Mass spectrum of a putative Ins1C-ChgA (PQVEQLEL-WSRMDQLAK) peptide in the islet MHCII peptidome (upper) that failed to match the synthetic standard peptide (middle). Further analysis suggested a probable correct match of the putative Ins1C-ChgA HIP to an Ins1C peptide fragment with sodium adduct (lower).
