Objective To clone and express the Trichinella spiralis Tsp06172 gene in BL21.Methods The Tsp06172 gene was amplified with RT-PCR and then subcloned into the prokaryotic expression vector pET-28a.BL21 containing the recombinant plasmid pET-28a-Tsp06172 was induced with IPTG.The fusion protein was detected and identified with SDS-PAGE and Western blotting.Results The recombinant expression plasmid was successfully constructed.After induction in an E.coli system,SDS-PAGE results showed that a fusion protein o...
