84-1090-56　Superoxide Dismutase, Cu,Zn (SOD Cu,Zn) 100ul　S8060-09D

特徴

• Superoxide dismutase (SOD) is an endogenously produced intracellular enzyme present in almost every cell in the body (3).
• It works by catalyzing the dismutation of the superoxide radical O2¯ to O2 and H2O2, which are then metabolized to H2O and O2 by catalase and glutathione peroxidase (2,5).
• In general, SODs play a major role in antioxidant defense mechanisms (4).
• There are two main types of SOD in mammalian cells.
• One form (SOD1) contains Cu and Zn ions as a homodimer and exists in the cytoplasm.
• The two subunits of 16 kD each are linked by two cysteines forming an intra-subunit disulfide bridge (3).
• The second form (SOD2) is a manganese containing enzyme and resides in the mitochondrial matrix.
• It is a homotetramer of 80 kD.
• The third form (SOD3 or EC-SOD) is like SOD1 in that it contains Cu and Zn ions, however it is distinct in that it is a homotetramer, with a mass of 30 kDA and it exists only in the extra-cellular space (7).
• SOD3 can also be distinguished by its heparinbinding capacity (1).
• Applications:Suitable for use in Western Blot, Immunoprecipitation, ELISA and Immunohistochemistry.
• Other applications not tested.
• Recommended Dilution:Western Blot: 0.5ug/ml was sufficient for detection of Cu/Zn SOD in 20ug of rat brain tissue extract by colorimetric immunoblot analysis using Goat anti-rabbit IgG:AP as the secondary antibody
• Optimal dilutions to be determined by the researcher.
• Storage and Stability:May be stored at 4°C for short-term only.
• For long-term storage, store at -20°C.
• Aliquots are stable for at least 12 months at -20°C.
• 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.
