Recombinant Human Cu/Zn Superoxide Dismutase, His (rHuCu/Zn SOD, His )

• Catalog Number: orb1495067
• Category: Proteins
• Description: Human Cu/Zn Superoxide Dismutase (SOD) 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.
• Form/Appearance: Lyophilized from a 0.2mm filtered concentrated solution in PBS, pH 7.4.
• Purity: > 95% by SDS-PAGE and HPLC analyses.
• MW: Approximately 20.0 kDa. a homodimer, non-glycosylated polypeptide chain containing 189 amino acids with 10 x His at the N-terminal.

• Source: Escherichia coli.
• Biological Activity: Fully biologically active when compared to standard. The potency per mg was tested by Pyrogallic Acid method and was found to be more than 10,000Units/mg.
• Endotoxins: Less than 1EU/mg of rHuSOD, His as determined by LAL method.
• Storage: This lyophilized preparation is stable at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -70°C. Avoid repeated freeze/thaw cycles.
• Buffer/Preservatives: Lyophilized from a 0.2mm filtered concentrated solution in PBS, pH 7.4.
• Note: For research use only
• Application notes: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at < -20°C. Further dilutions should be made in appropriate buffered solutions.
• Expiration Date: 6 months from date of receipt.
