一般說明
该产品作为过氧化物酶的即用型单组分底物提供,所述过氧化物酶在酸性缓冲液中由 2,2′-联氮-双(3-乙基苯并噻唑啉-6-磺酸)组成。底物与过氧化物酶反应前无色,与之反应后产生蓝绿色的显色反应产物。在终点检测期间,可使用 1% 十二烷基硫酸钠 (SDS) 终止反应。由于该底物会产生可溶性反应产物,因此不推荐用于免疫印迹或组织化学应用。
應用
2,2'-叠氮化合物-双(3-乙基苯并噻唑啉-6-磺酸)已被用作 ELISA 实验中的过氧化物酶底物。该底物得到绿色可溶性最终产物。它也被用来作为一种胶体制剂散布在标准的培养基平板上,以评估木质素的氧化活性。底物呈绿色显示微生物漆酶活性。
生化/生理作用
2,2'-联氮-双(3-乙基苯并噻唑啉-6-磺酸)(ABTS) 是一种阳离子,在过氧化氢存在下发生氧化。氧化 ABTS 为蓝绿色产品,可通过比色法测量。ABTS、过氧化氢和肌红蛋白相结合可用作测量样本总抗氧化能力 (TAC) 的标准系统。ABTS 方法在不同 pH 值下具有灵活性,并且应用最广泛。ABTS 是酚氧化酶的底物。
