| Abstract: | According to published HA1 gene H5 subtype sequence of avian influenza virus(AIV) in Genbank,a pair of primers were designed and synthesized.Using the primers,a gene of approximately 1 000 bp in length was amplified by RT-PCR,then it was inserted into the plasmid vector pPROEX-HTb,the recombinant plasmid was identified by PCR and expressed in Escherichia coli.The results showed that an expected fusion protein of 38 ku in size was successfully expressed which had right immunity by western-blotting. |
