Fig. 3. SDS-PAGE analysis and the solubility of expressed His-AmSOD1 in the strain R-AmSOD1 harboring pET28a-AmSOD1 (A) Total soluble protein extracted from control strain and the strain R-AmSOD1 before and 1–4 h after induction with IPTG. (B) The study of solubility of His-AmSOD1 by comparison of His-AmSOD1 band intensities in the total protein (T), the soluble fraction extracted from R-AmSOD1 (S) and the unsoluble fraction (U) extracted from RAmSOD1 (The recombinant proteins were shown with arrows) (C) SDS-PAGE analysis of AmSOD1 after purification with affinity chromatography.
