The binding capacity of the peptides was scored according to the presence of anchor amino acids and other amino acids frequently occurring in natural ligands (20).
Peptides possessing H-2b-binding anchor residues were tested for the ability to bind to class I molecules in vitro as described in Materials and Methods. ND, not determined; +++, strong stabilization of MHC assembly by peptide; +, stabilization of MHC assembly by peptide.
