超氧化物歧化酶(Superoxide dismutases , SOD,EC1.15.1.1)是催化超氧化物陰離子(superoxide anion)分解為O2和H2O2的酶。 它們是抵抗暴露於O2的所有細胞中超氧自由基(superoxide radical)毒性的重要抗氧化劑(antioxidant defense against)。 SOD異常活動與肌萎縮性側索硬化(amyotrophic lateral sclerosis),圍產期致死率(perinatal lethality),神經疾病(neural disorders)和癌症(cancer)等疾病有關。 超氧化物歧化酶(superoxide dismutase)有三個主要家族:Cu / Zn,Fe / Mn和Ni型。 人類中存在三種形式的超氧化物歧化酶(superoxide dismutase)。 SOD1位於細胞質(cytoplasm)中,SOD2位於線粒體(mitochondria)中,SOD3位於細胞外(extracellular)。測定血清、血漿、組織/細胞裂解液和其他生物體液中的 SOD 酶活性。 WST-8法測定SOD活性,最大抑制率可接近100%,不受一些常見干擾因素的干擾。廣泛的線性範圍:3.13-200U/mL。

超氧化物歧化酶 (SOD) 是一種抗氧化酶,參與針對活性氧 (ROS) 的防禦系統。SOD催化超氧自由基陰離子(O 2 -)歧化反應生成過氧化氫,過氧化氫再被穀胱甘肽過氧化物酶和過氧化氫酶催化生成無害的O 2和H 2 O。已經確定了幾種類型的 SOD。這些包括細胞內銅、鋅 SOD(Cu、Zn SOD/SOD1)、線粒體錳 SOD(Mn SOD/SOD2)和細胞外 Cu、Zn SOD(EC SOD/SOD3)。
Determination of SOD enzyme activity in serum, plasma, tissue/cell lysates and other biological fluids.
• Determining SOD activity by WST-8 method, the maximum inhibition percentage can be close to 100 %, and it can not be interfered by some common interfering factors.
• A broad range linearity: 3.13- 200U/mL.

CheKine™超氧化物歧化酶(SOD)活性測定試劑盒(CheKine™ Superoxide dismutase (SOD) Activity Assay Kit, 貨號KTB1030)為定量測定血清(serum),血漿(plasma),組織(tissue)/細胞裂解液(cell lysates)和其他生物液體(biological fluids)中的SOD酶活性(SOD enzyme activity)提供了一種簡便的比色測定法(colorimetric assay)。 在測定中,黃嘌呤氧化酶(xanthine oxidase, XO)催化反應提供了超氧陰離子(superoxide anion , O2-)。 O2-與四唑鎓鹽WST-8染料( tetrazolium salt WST-8 dye)反應生成水溶性 formazan產物。 SOD清除了O2-,因此用於顯色反應的O2-較少。 通過比色法在OD 450nm下測量SOD的這種抑制活性。由於SOD試劑盒(KTB1030)報告為抑制%,因此可以不使用標準試劑。 樣品中的SOD越多,產生的 less WST-8 formazan產物(這取決於黃嘌呤氧化酶(XO)活性)。
Abbkine CheKine™ Superoxide dismutase (SOD) Activity Assay Kit provides a simple and easy colorimetric assay for the quantitative determination of SOD enzyme activity in serum, plasma, tissue/cell lysates and other biological fluids. In the assay, superoxide anion (O2-) is provided by xanthine oxidase (XO) catalyzed reaction. O2- reacts with a tetrazolium salt WST-8 dye to form a water-soluble colored formazan product. SOD scavenges the O2- thus less O2- is available for the chromogenic reaction. This inhibition activity of SOD is measured by colorimetric method at OD 450 nm.
