Kinetic stability of peptide:MHC complex composed by DR0401 or DR0403 with selected GAD65 derived peptides. (A) DQ8 bound GAD65 peptides also bind DR0401 (within black line circle) and/or DR0403 (within blue line circle). The dissociation of GAD65p24 (B), p25 (C), p26 (D), p34 (E), p42 (F) and p67 (G) from HLA-DR0401 (black circles, solid lines) and HLA-DR0403 (open circles, dotted lines) was measured as the remaining amount of biotinylated target peptides against experimental time. The dissociation curves were generated with a single-exponential decay fit [Equation: Y= Span*exp(−Kd*X)+Plateau].
