• a Values are expressed as the relative affinity, i.e., the ratio of the IC50 of the test peptide to the IC50 of a reference peptide chosen as a high binder for each allele. High- and intermediate-affinity vales were interpreted as follows: <10, high affinity; <100, intermediate affinity (both types of values are indicated in boldface).
