Cat#:RP-5812H;Product Name:Recombinant Human SOD Protein;Synonym:Superoxide dismutase [Cu-Zn], EC 1.15.1.1, SOD1, SOD, ALS, ALS1, IPOA.;Description:Recombinant Human Cu/Zn Superoxide Dismutase produced in E.coli is a homodimer, non-glycosylated polypeptide chain containing 2 x 154 amino acids and having a total molecular mass of 31,608 Dalton. The Cu/Zn SOD is purified by proprietary chromatographic techniques.;Source:E.coli;AA Sequence:The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Thr-Lys-Ala-Val.;Purity:Greater than 95.0% as determined by(a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.;Bioactivity:The potency per mg was tested by Pyrogallic Acid method and was found to be more than 10,000 Units/mg.;Formulation:Lyophilized from a 0.2μm filtered concentrated (1mg/ml) solution in PBS, pH 7.4.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized SOD in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized SOD although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution SOD should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.;
