一般說明
刃天青(Resazurin)是二羟基吩噁嗪酮的N-氧化小分子衍生物。它是一种非离子染料，含有小的平面发色团。它是一种氧化还原指示剂，反应时由蓝紫色变为粉红色再变为无色。它也可用作3.5-6.5范围的pH指示剂，颜色由橙色变为蓝紫色。它的商品化形式为刃天青钠盐，也称3H-吩恶嗪-3-酮, 7-羟基-, 10-氧化物钠盐。经还原作用形成红色荧光的试卤灵（羟基吩噁嗪酮），进一步还原形成无色的氢化试卤灵。
應用
刃天青最常用作生物氧化还原指示剂。染料的生物还原减少了其氧化形式（蓝色）的含量，同时增加了荧光中间体（红色）水平。其应用包括：
- 测定酶活力和活细胞的增殖
- 检测乳汁中的细菌还原作用
- 在活力测定中用作检测活细菌的培养基成分
- 测定绵羊精液中活动精子的数目
- 检测乳酸脱氢酶
- 作为定量测定L-谷氨酸盐的分析试剂
用于测量活细胞的代谢活性和增殖。染料的生物还原减少了其氧化形式（蓝色）的含量，同时增加了荧光中间体（红色）水平。
