The N gene ORF was then subcloned into pET-30a vector and the recombinant plasmid was transformed into E.coli BL21 (DE3) and induced with IPTG. The protein expression was determined by SDS-PAGE. The expressed protein had a molecular weight of 54.4 Ku that existed as inclusion body. Thin-layer scanning showed that the expression product accounted for 30.5% of the total bacterial proteins. The recombinant protein possessed native biological activity and could react with anti-PEDV hyperimmune serum in Western blot.

Methods The target cDNA was amplified by PCR and PCR products were indigested by restriction enzyme Nco Ⅰ and Hind Ⅲ. Then the indigested products were recombined into pET-BBH and pET-BBH was expressed in E. coli BL21 (DE3) by IPTG inducing. Next, the expressed proteins were identified by SDS-PAGE, western blot and enzyme activity test. Finally, fluorescence quantitative PCR was used to test its expression quantity in different worm stages.
