Fig. 2. SDS-PAGE analysis of GST and GST–AmMT2. (A) Total soluble proteins extracted from E. coli harboring pET41a and pET41a-AmMT2 at 0, 1, 2, 3 and 4 h after addition of IPTG. (B) The GST-OsMTI-2b was purified using affinity chromatography (lane P). The white arrows show the bands corresponding to GST and the black arrows show the band corresponding to GST-AmMT2.
