Purpose: To express, purify and characterize recombinant mouse Cu/Zn-binding superoxide dismutase (mSOD1), and investigate its activity in vitro. Methods: The protein, mSOD1, was expressed after induction with isopropyl-beta-Dthiogalactopyranoside (IPTG). The target protein was purified by Ni-NTA affinity chromatography. The identity of the recombinant protein was confirmed by Western-blot and peptide mass fingerprinting (PMF) analysis. Protein activity in vitro was investigated by SOD activity assay kit and DNA damage protective assay. Results: mSOD1 protein was expressed with a final yield of about 60 mg of pure protein per liter of culture medium. After purification, the target protein was > 95%. The identity of the recombinant protein was confirmed. SOD activity assay showed that the highest activity of the mSOD1 was 3789.0 ± 80.5 U/mg. The present work showed that mSOD1 was effective in protecting DNA from oxidative damage. Conclusion: High purity recombinant mSOD1 was obtained and characterized, and had high activity in vitro. The study indicates that the mSOD1 may serve as a potential therapeutic agent for those diseases caused by oxidative stress. © Pharmacotherapy Group, Faculty of Pharmacy, University of Benin, Benin City, 300001 Nigeria.
