We constructed a Mycobacterium tuberculosis vector expressing CFP-10 and Rv2626c to examine the expression of these proteins in Escherichia coli as well as their immunoreactivity. The CFP-10 and Rv2626c genes were amplified from tuberculosis H37Rv genomic DNA using polymerase chain reaction. They were ligated into the expression vector PET30a and expressed in E. coli. Histidine tag nickel column chromatography was used to purify the recombinant protein. An enzyme-linked immunosorbent assay (ELISA) was used for detection. In our E.
