Superoxide Dismutase Human Recombinant His Tag

Human Cu/Zn Superoxide Dismutase (SOD1) catalyzes the reaction between superoxide anions and hydrogen to yield molecular oxygen and hydrogen peroxide. The enzyme protects the cell against dangerous levels of superoxide. SOD1 binds copper and zinc ions and is 1 of 3 isozymes accountable 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.
Description SOD Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 189 amino acids with a 10 × His at N-terminus and having a molecular mass of 40.0kDa.
The SOD Human is purified by proprietary chromatographic techniques.
Synonyms Superoxide dismutase [Cu-Zn], EC 1.15.1.1, SOD1, SOD, ALS, ALS1, IPOA.
Source Escherichia Coli.

Purity >96% as determined by SDS-PAGE and HPLC
Formulation Sterile Filtered White lyophilized (freeze-dried) powder.
Lyophilized from a 0.2um filtered concentrated solution in PBS, pH 7.4.
Stability The lyophilized form of the protein is stable at room temperature for 3 weeks and at -20°C for at least 2 years from the date of receipt. Upon reconstitution, the protein should be stored at 4°C for no more than 7 days. The protein is stable at -20°C for six months. For long term storage, please store at -80°C and the addition of a carrier protein (0.1% HSA or BSA) is recommended. Please prevent freeze-thaw cycles.
Biological Activity Fully biologically active when compared to standard. The specific activity was tested by Pyrogallic Acid method and was found to be more than 10,000Units/mg.
Solubility It is recommended to reconstitute the lyophilized SOD in sterile 18M?-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Usage LABORATORY RESEARCH USE ONLY. Not intended for diagnostic or therapeutic purposes.
