Hydroxyl Free Radical Scavenging Capacity Assay Kit

CheKine™ Hydroxyl Free Radical Scavenging Capacity Assay Kit

CheKine™羥自由基清除能力測定試劑盒(Hydroxyl Free Radical Scavenging Capacity Assay Kit, KTB1090),為研究各種樣品中的羥自由基清除能力(Hydroxyl radical scavenging Capacity)，提供了一種簡便的比色法。在該測定中，H2O2 / Fe2 +通過Fenton反應產生羥基自由基(hydroxyl radical )，並將Fe2 +氧化為Fe3 +，導致536nm吸光度降低。樣品在536nm吸光度降低時的抑制率可以反映樣品的羥自由基清除能力(Hydroxyl Free Radical Scavenging Capacity)。羥基自由基•OH是氫氧根離子（OH-）的中性形式，具有高反應性（易於變成羥基），因此壽命短。但是，它們是自由基化學的重要組成部分。最明顯的是，羥基自由基是由氫過氧化物（hydroperoxides , ROOH）的分解產生的，或者在大氣化學中是由激發的原子氧(excited atomic oxygen)與水的反應產生的。羥基幾乎可以破壞所有類型的大分子：碳水化合物(carbohydrates)，核酸(nucleic acids)（突變），脂質（lipid peroxidation, 脂質過氧化）和氨基酸（例如Phe轉化為m-酪氨酸(m-Tyrosine)和o-酪氨酸(o-Tyrosine），導致細胞結構(cell structure)和功能受損(function damage)，然後導致新陳代謝失調(metabolic disorders)。羥基自由基的清除能力代表了抗氧化能力，廣泛用於抗氧化保健品(antioxidant health products)和藥物的研究。
