Predicted and measured binding affinities. Correlation between predicted half-life of binding of 17 Ig-derived native (▪) and 17 heteroclitic (▴) peptides to HLA-A*0201 of (A) predicted binding as assessed by the Parker score and the Rammensee score, (B) predicted binding according to the Parker Score and measured binding as calculated by the FI, and (C) predicted binding according to the Rammensee score and measured binding as calculated by the FI.
