Na Kong, Expression of Recombinant Baculovirus Vetor Double-expressing HA1 Gene from H5 Subtype Avian Influenza Virus and Mature Chicken Interleukin-18 Gene, Journal of Animal and Veterinary Advances, Volume 14,Issue 5, 2015, Pages 136-139, ISSN 1680-5593, javaa.2015.136.139, (https://makhillpublications.co/view-article.php?doi=javaa.2015.136.139) Abstract: The Hemagglutinin (HA1) gene from H5 subtype Avian Influenza Virus (AIV) and mature Chicken Interleukin-18 (mChIL-18) gene were amplified by designing two pairs of primers according to the sequence published on GenBank. The HA1 gene and mChIL-18 gene were inserted into the downstreams of PH promoter and P10 promoter of baculovirus expression plasmid pFastBacTMDual, respectively. The recombinant pFastBacTMdual-mChIL-18-HA1 (rIL18-HA1) was ransformed into DH10Bac competent cells and expressed in sf9 cells by IFA diction. The results showed that the recombinant protein IL18-HA1 (pIL18-HA1) was simultaneouly expressed in the same sf9 cells with IL18 protein and HA1 protein, respectively. It is the foundation for developing a neotype vaccine against AIV. Keywords: Avian influenza virus;HA1 gene;mature ChIL-18 gene;eukaryotic expression;IL18 protein
