Recombinant DQ2 (4.7 μM) was mixed with fluorescein-conjugated peptide (0.185 μM) at 37°C for 45 h at pH 5.5. The formation of 2:1 DQ2-peptide complex with two DQ2 molecules binding to one peptide was reported as the percentage among total DQ2-peptide complex, i.e. [2:1 complex] / ([2:1 complex] + [1:1 complex]) ×100%.
