超氧化物歧化酶(Superoxide dismutase,SOD)是一种广泛存在于动物、植物和微生物中的抗氧化的金属酶,按照结合金属离子种类不同,该酶有以下三种:含铜与锌超氧化物歧化酶(Cu/Zn-SOD)、含锰超氧化物歧化酶(Mn-SOD)和含铁超氧化物歧化酶(Fe-SOD),三种 SOD 都催化超氧化物阴离子自由基歧化生成过氧化氢与氧气。
由于细胞自由基非常活泼,参与一系列的化学反应,能引起细胞生物膜上的脂质过氧化,破坏了膜的结构和功能,使体内的许多酶及激素失去生物活性,同时还能破坏核酸结构和导致整个机体代谢失常与病变。
作为专业的生命科学医药原料供应商,Cell Biolabs中国区金牌代理,艾美捷科技为您推荐:超氧化物歧化酶SOD活性分析试剂盒
产品 | 超氧化物歧化酶SOD活性分析试剂盒 OxiSelec Superoxide Dismutase Activity Assay |
货号 | STA-340 (100 assays) |
检测方法 | 比色法 |
样本类型 | 悬浮细胞,贴壁细胞,组织裂解液,血清/血浆 |
检测范围 | 1.2 mU/ul — 5U/ul |
说明书下载 | 点击下载 |
实验原理 | 通过使用黄嘌呤(Xanthine)/黄嘌呤氧化酶(XOD)体系生成超氧化物阴离子。加入发色基团,发色基团可被由上述体系产生的氧化物阴离子还原成为水溶性的黄色甲染料,这样SOD活性通过抑制发生基团的还原来测定。当存在SOD时,超氧阴离子浓度降低,产生的颜色信号下降。 |
试剂盒组分 | 1. SOD Standard 2. Xanthine Solution 3. Xanthine Oxidase Solution, 150X 4. Chromagen Solution 5. SOD Assay Buffer, 10X |
保存条件 | 收到后,将试剂盒保存在-20℃,避免多次反复冻融 |
* 本产品仅适用于科研用途.
FAQ常见问题:
1.超氧化物歧化酶SOD活性分析试剂盒,有物种种属限制吗?
我们的SOD活性试剂盒,适用于任何生物蛋白质样品,因为它使用黄嘌呤/黄嘌呤 氧化酶方法测量酶活性,并不依赖于可能因物种而异的蛋白质结构。
2.是否可以检测冻存过的样本?
我们的超氧化物歧化酶SOD活性分析试剂盒通常适用于在 -80?C 下保存两个月以内样品,但我们建议尽可能测试新鲜样品以获得最佳结果。
3.你们的超氧化物歧化酶SOD活性分析试剂盒可以检测3种SOD酶吗?
我们的SOD活性试剂盒,可以检测所有类型的SOD酶,包括含铜与锌超氧化物歧化酶Cu/ Zn-SOD,含锰超氧化物歧化酶Mn-SOD,以及含铁超氧化物歧化酶Fe-SOD。
