Hyung-Kwan Jang 대한수의학회 Journal of Veterinary Science 7 Pages
대한수의학회 Journal of Veterinary Science 2004, 제 5권 제 3호 4 207-213 (7 pages)
Studies on Marek’s disease virus (MDV)-unique genes are important for understanding the biological nature of the virus. Based on complete DNA sequence analyses of the MDV genomes, the MDV genomes contain presumably at least five MDV-unique genes, which are commonly conserved among the three MDV serotypes. A recombinant baculovirus that contains the MDV serotype 2 (MDV2)-unique gene, ORF873, under the polyhedrin promoter was constructed and designated rAcORF873. Polyclonal and monoclonal... -
