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.
