POLYEPITOPE PROTEIN, NUCLEOTIDE SEQUENCE CODING POLYEPITOPE PROTEIN, PLASMID WITH SEQUENCE CODING POLYEPITOPE PROTEIN, AND PREPARATION OF POLYEPITOPE PROTEIN FOR INDUCTION OF IMMUNE RESPONSE ON MURRAIN VIRUS

摘要

FIELD: medicine.;SUBSTANCE: invention refers to a polyepitope vaccine protein applicable for immunisation against murrain virus, nucleic acid coding this protein, recombinant plasmid pA7248-AMV-H-PE for production of said protein in plants and to a vaccine preparation for prevention and protection against infection caused by murrain virus. The polyepitope vaccine protein has the amino acid sequence SEQ ID NO: 1 which contains the amino acid sequence of B-cell epitope of VP4 protein from 21-th to 40-th amino acid starting with N-terminal, the amino acid sequence of B-cell epitope of VP1 protein from 135-th to 160-th amino acid starting with N-terminal, the amino acid sequence of B-cell epitope of VP1 protein from 200-th to 213-th amino acid starting with N-terminal, the amino acid sequence of T-cell epitope of 2C protein from 68-th to 76-th amino acid starting with N-terminal, the amino acid sequence of T-cell epitope of 3D protein from 1-st to 115-th amino acid starting from N-terminal, and the amino acid sequence of T-cell epitope of 3D protein from 421-st to 460-th amino acid of murrain virus serotype O/ Taiwan/99. Nucleic acid coding such protein has the nucleotide sequence SEQ ID NO: 2. Recombinant plasmid pA7248-AMV-H-PE has a physical map presented in dwg. 5.;EFFECT: invention provides creating polyepitope vaccine protein which is applicable for immunisation against murrain virus.;5 cl, 7 dwg, 2 tbl, 6 ex
