ABSTRACT
Infectious bursal disease virus (IBDV) VP5 gene was amplified and cloned into an N-terminal GST-Tag fusion expression vector, pGEX-4T-2, which was controlled by T7 promoter. The sequencing result showed that the VP5 gene was composed of 438 base pairs, and coded 145 amino acids. High VP5 product was expressed in E. coli BL21 induced by IPTG, and the GST-VP5 fusion protein existed in inclusion. High titer anti-VP5 serum was also prepared in New Zealand rabbit immunized with purified fusion protein inclusion. These results gave a basis for further research for VP5 function in IBDV replication and pathogenicity, which also paved the way for developing VP5 gene deleted IBDV live vaccine.
