Hybrid antigen protein, recombined virus for expressing the same, and its production

PURPOSE:To provide the hybrid antigen protein having a virus-constituting protein and the small peptide epitope of a pathogenic virus and useful as a vaccine or a diagnostic medicine. CONSTITUTION:The hybrid antigen protein having the virus-constituting protein and the small peptide epitope of the pathogenic virus is produced by preparing a recombined virus having the gene of the virus-constituting protein and the gene of the small peptide epitope of the pathogenic virus and subsequently allowing the recombined virus to express in the cultured cell.
