Comparison among the cDC, MHC II-eluted, and lymph peptidomes.
a, MS/MS fragmentation of the thymosin β4 peptides found in the lymph and eluted from MHC II. b and c, MS/MS fragmentation of the C3 peptides found in the lymph and eluted from MHC II. d, MS/MS fragmentation of one of the I-Eα peptides found in the lymph and eluted from MHC II.
