Abstract

Antigens, immunogens, inocula, antibodies, diagnostic methods and systems relating to Epstein-Barr virus nuclear antigen (EBNA) are disclosed. Each of the compounds, compositions, methods or systems contains a synthetic, random copolymer polypeptide having about 6 to about 40 residues, or an antibody containing site that immunoreacts with such a polypeptide. The polypeptide includes the five amino acid residue sequence -Gly-R.sup.1 -Gly-R.sup.2 -Gly-, wherein R.sup.1 and R.sup.2 are the same or different amino acid residues selected from the group consisting of Ala, Asn, Arg, Gly, Leu, Pro, Ser, and Thr, with the provision that R.sup.1 and R.sup.2 are not both Gly. The polypeptide contains at least 25 mole percent Gly residues, and when linked to a carrier and introduced in an effective amount into a mammalian host is capable of inducing production of antibodies that immunoreact with EBNA.
