The presence of a strong expressed protein band was visualized on SDS-gel with a molecular weight of 21.78 kDa in cell lysate. (Lane 1): Protein marker, (Lane 2): Transformed E. coli cell lysates before induction with IPTG, (Lane 3): Transformed E. coli cell lysates after 18 h induction with 0.5 mM IPTG, where the presence of a strong expressive protein is shown at a weight of 21.78 kDa, (Lane 4): Purified denatured fusion protein. Please note that the uncropped original SDS-gel image is shown in Additional file 1: Fig. S1
