I-Ad-binding peptides derived from unrelated protein antigens share a common structural motif
Udgivelsesdato: 1988-Jul-1 Purified Ia molecules can specifically bind many unrelated peptide Ag, and such binding appears to be a necessary, albeit not sufficient, prerequisite for the immunogenicity of the proteins from which such peptides are derived. We have recently analyzed the affect of singl...
