The aim of this study was to investigate the prokaryotic expression of hemocyanin subunit type 1gene from Locusta migratoria manilensis and predict the protein structure.A recombinant strain which could express antigen of Lmi Hc1was constructed.Lmi Hc1gene was amplified by PCR.The DNA products of Lmi Hc1were inserted into a prokaryotic expression vector pET-DsbA,and then translated in- to E.coli strain BL21(DE3).SDS-PAGE electrophoresis was analyzed.The prokaryotic expression vector of Lmi Hc1gene was succe...
