Assay
1. Prepare a 180ul assay buffer mix into a suitable container and pre-chill on ice before use: The concentrations are 54mM potassium phosphate, 5.5mM ethylendiaminetetraacetic acid, 66mM
cytochromC 0.9mM xanthine, 0.01 units xanthine oxidase. 2. Equilibrate to 25C and monitor at A550nm until the value is constant using a spectrophotometer.
3. Add 20ul of recombinant SOD1 protein to 50ug/ml in assay buffer.
4. Mix by inversion and record the increase at A550nm for 5 minutes.

Related Product Information for SOD1 active protein
Superoxide dismutase 1 (SOD1) binds copper and zinc ions and is one of three isozymes responsible for destroying free superoxide radicals in the body. The encoded protein neutralizes supercharged oxygen molecules, which can damage cells if their levels are not controlled. Mutations in SOD1 cause a form of familial amyotrophic lateral sclerosis (ALS). Recombinant SOD1 was expressed in E Coli and purified by conventional chromatography techniques.

NCBI Description
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. 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 2008]
Uniprot Description
Destroys radicals which are normally produced within the cells and which are toxic to biological systems.
