  1. Prepare a 1.5 ml reaction mix into a suitable container and pre-chill on ice before use: The final concentrations are 50 mM potassium phosphate, 0.1 mM ethylendiaminetetraacetic acid, 0.01 mM cytochrom C, 0.05 mM xanthine, 0.005 units xanthine oxidase.
  2. Equilibrate to 25°C and monitor at A550nm until the value is constant using a spectrophotometer.
  3. Add 50 ul of recombinant SOD protein in various concentrations (0.5ug, 1ug) in assay buffer.
  4. Mix by inversion and record the increase at A550nm for 5 minutes.
• Protein Description: Recombinant SOD1 was expressed in E.coli and purified by conventional chromatography techniques.

• Summary: The protein encoded by this gene binds copper and zinc ions and is one of two isozymes responsible for destroying free superoxide radicals in the body. The encoded isozyme is a soluble cytoplasmic protein, acting as a homodimer to convert naturally-occuring but harmful superoxide radicals to molecular oxygen and hydrogen peroxide. The other isozyme is a mitochondrial protein. In addition, this protein contains an antimicrobial peptide that displays antibacterial, antifungal, and anti-MRSA activity against E. coli, E. faecalis, S. aureus, S. aureus MRSA LPV+, S. agalactiae, and yeast C. krusei. Mutations in this gene have been implicated as causes of familial amyotrophic lateral sclerosis. Rare transcript variants have been reported for this gene. [provided by RefSeq, Jul 2020]
