生物活性/药理作用 | Catalyzes the dismutation of superoxide radicals to hydrogen peroxide and molecular oxygen. Plays a critical role in the defense of cells against the toxic effects of oxygen radicals. Competes with nitric oxide (NO) for superoxide anion (which reacts with NO to form peroxynitrite), thereby SOD promotes the activity of NO. SOD has also been shown to suppress apoptosis in cultured rat ovarian follicles, neural cell lines, and transgenic mice. |
样品准备说明 | SOD is soluble in water (20 mg/ml) yielding a colorless to blue-green solution. SOD is also soluble in aqueous buffers such as 0.1 M potassium phosphate, pH 7.5. |
有效单位定义 | One unit will inhibit reduction of cytochrome c by 50% in a coupled system with xanthine oxidase at pH 7.8 at 25°C in a 3.0 mL reaction volume. Xanthine oxidase concentration should produce
an initial ΔA550 of 0.025 ± 0.005 per min. |
