Cloning, expression and purification of the recombinant FliC from Salmonella enteritidis

Abstract

FliC protein from Salmonella enteritidis is currently interested due to its immunologic adjuvant property for the novel generation of recombinant vaccines. To produce a source for further researches on the immune effects of FliC, we generated an Escherichia coli based on recombinant vector called pET-fliC which is ligated from fliC gene with NdeI and XhoI double digested pET vectors. The results of expression of recombinant FliC, which was induced by IPTG, were confirmed by SDS-PAGE and Western blot probed with anti-6xHis tag. With the purity above 95 %, this recombinant FliC can be used as a material source for next studies on evaluating the adjuvant property of FliC.
