Purified recombinant Human SOD1 protein Expression System: E.coli Bioactivity: Specific activity is > 90 units/mg, in which one unit will inhibit the rate of reduction of cytochrome c by 50 % in a coupled system, using xanthine and Xanthine oxidase at pH 7.8 at 25 °C in a 1.5 ml reaction volume. Molecular weight on SDS-PAGE will appear higher.

Testdurchführung
Prepare a 1.5 mL reaction mix in a suitable container and pre-chill on ice before use: The final concentrations are 50 mM potassium phosphate, 0.0 mM ethylendiaminetetraacetic acid, 0.00 mM cytochromC 0.00 mM xanthine, 0.005 units xanthine oxidase. 2. Equilibrate to 25 °C and monitor at A550 nm until the value is constant using a spectrophotometer. 3. Add 50 µL of recombinant SOD protein in various concentrations (0.5 µg, 5 µg) in assay buffer. 4. Mix by inversion and record the increase at A550 nm for 5 minutes.

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.
