TUMOR ANTIGEN PEPTIDE DERIVATIVES

摘要

Tumor antigen peptide derivatives containing the whole amino acid sequence derived from the amino acid sequence Glu Tyr Arg Gly Phe Thr Gln Asp Phe (SEQ ID NO:3) by altering one to several amino acid residues or a part thereof and capable of binding to HLA-A24 antigen and thus being recognized by cytotoxic T cells; the use of these tumor antigen peptide derivatives in treating, preventing and diagnosing tumors; and remedies or preventives for tumors containing these peptide derivatives as the active ingredient.
