Abstract

Objective To construct and express a recombinant plasmid pGEX-Sj26GST of Schistosoma japonicum(Sj)in Escherichia coli(E.coli)BL21(DE3).Methods Total RNA was extracted from Sj adult worms by RNeasy Mini kit,26 kilodalton glutathione-S-transferases of Schistosoma japonicum(Sj26GST)antigen gene was amplified by real-time PCR(RT-PCR)from the total RNA,then cloned into a prokaryotic expression plasmid pGEX-1λT and transformed into E.coli BL21(DE3)to construct pGEX-Sj26GST;BL21(pGEX-
