Expression of antigenic Epstein-Barr virus polypeptides in bacteria and their use in diagnostics

摘要

Bacterially synthesized polypeptides that are recognized by antibodies produced in EBV-infected humans are disclosed. Plasmids containing DNA sequences encoding portions of the EBNA and EBEA-D antigens are also disclosed, as are methods for expressing these DNA sequences in bacteria. The DNA sequence encoding the EBNA-1-related fusion polypeptide is found in a Bam H1 K-restriction fragment, while that encoding the EBEA-D-related fusion polypeptide is found in a Bam H1 M-restriction fragment.
