总抗氧化能力检测试剂盒

Antioxidants are a group of free radical scavengers, including macro and micro molecules (transferrin, vitamin E, etc.) and enzymes (catalase, GSH reductase, etc.), that can protect vital cellular target against oxidative attack from free radicals or reactive oxygen species (ROS). Due to the chemical diversity and cooperative nature of antioxidants, the measurement of total antioxidant capacity (TAC) is important in monitoring the clinical status of body fluids, as well as the cumulative capability of various food supplements to counteract oxidative stress. The ScienCell Total Antioxidant Capacity (TAC) Assay is a cupric ion reducing antioxidant capacity (CUPRAC) spectrophotometric method, which can simultaneously measure hydrophilic and lipophilic antioxidants at physiological pH. Trolox, a cell-permeable, water-soluble derivative of vitamin E with antioxidant properties, serves as a standard.

抗氧化剂是一类清除自由基的物质，包括大分子和小分子（如转铁蛋白、维生素E等）以及酶类（如过氧化氢酶、谷胱甘肽还原酶等），可保护细胞内关键靶标免受自由基或活性氧（ROS）的氧化攻击。

由于抗氧化剂在化学性质上的多样性及其协同作用，测定总抗氧化能力（TAC）对于监测体液的生理状态以及评估各类膳食补充剂抵御氧化应激的综合能力具有重要意义。

ScienCell 总抗氧化能力（TAC）检测试剂盒采用基于铜离子还原抗氧化能力（CUPRAC）的分光光度法，可在生理pH条件下同时检测亲水性和亲脂性抗氧化剂。Trolox（维生素E的一种可透细胞、水溶性衍生物，具有抗氧化特性）作为标准品使用。
