Rv2159c cloning, expression and purification. (A,B) SDS-PAGE (12% gel) separation of proteins and western immunoloblot with anti-GST antibody of E. coli BL21 cells expressed Rv2159c protein. Lane 1 shows the resolution of cytosolic proteins of BL21 cells (negative control); lane 2, BL21 cells expressed pDVA 2159-GST plasmid; lane 3 shows the purified recombinant GST-Rv2159c protein using glutathione sepharose affinity chromatography and lane M, protein molecular weight ladder.
