SKU:: S8060-13
Reinheit:: ≥95% by RP-HPLC and SDS-PAGE. Chromatographically purified.
Lagerbedingungen:: -20°C
Hersteller:: United States Biological
Format:: Supplied as a lyophilized powder from PBS, pH 7.4. Reconstitute in sterile ddH2O to ≥0.1mg/ml. Add 0.1% HSA or BSA for long term storage. This solution can then be diluted into other aqueous solutions.
Weitere Details:: An oxidoreductase that 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. Recombinant Human Cu/Zn Superoxide Dismutase is a homodimer, non-glycosylated polypeptide chain containing 2 x 154 amino acids and having a total molecular mass of 31,608D Amino Acid Sequence: The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Thr-Lys-Ala-Val. Biological Activity: The potency per mg was tested by Pyrogallic Acid method and was found to be more than 10,000Units/mg. Storage and Stability: Lyophilized and reconstituted products are stable for 6 months after receipt at -20°C. Reconstitute with sterile ddH2O to ≥0.1mg/ml. Add a carrier protein (0.1% HSA or BSA). Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
