abstract |
A synthetic polypeptide that contains about 6 to about 40 amino acid residues that immunologically mimics the early antigen-diffuse (EA-D) protein of the Epstein-Barr virus (EBV) is disclosed, as are receptors raised to that polypeptide, methods of their use and a reagent system. A polypeptide of the present invention has an amino acid residue sequence that corresponds to the sequence of the EBV EA-D protein from about position 350 to about position 362 from the amino-terminus. |
