Cu/Zn Human Superoxide Dismutase is a stable dimer of identical subunits with a combined molecular mass of 32Kd. This enzyme dismutes the superoxide radical to molecular oxygen. This enzyme has been expressed in yeast and purified using sequential chromatography steps. The hSOD is acetylated at its N-terminus. N-terminus. Biological Activity: The specific activity of SOD is 260 U/mg. The enzymatic activity of human SOD is determined by calorimetrically determining the oxidation of a chromophore. Storage and Stability: Lyophilized powder may be stored at -20C. Stable for 12 months at -20C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
