高度敏感且特异的荧光探针，可测量活细胞中的缺氧和氧化应激 适用于附着或悬浮细胞系 包括ROS和缺氧诱导剂在内的完整试剂盒 Enzo Life Sciences的ROS-ID®缺氧/氧化应激检测套装旨在功能性检测活细胞（悬浮和附着细胞均适用）中的缺氧和氧化应激水平，可使用荧光显微镜或流式细胞术。该套装包括缺氧（红色）和氧化应激水平（绿色）的荧光探针作为两个主要组成部分。
实验原理概述：
1、缺氧检测（红色）：缺氧检测试剂（Red Hypoxia Detection Reagent）是一种非荧光或弱荧光的芳香族化合物，含有硝基（NO2）基团。在缺氧细胞中，由于存在硝基还原酶活性，硝基团通过一系列化学反应被转化为羟胺（NHOH）和氨基（NH2）基团，导致原始分子降解并释放出荧光探针，从而在荧光显微镜下呈现红色荧光。
2、氧化应激检测（绿色）：氧化应激检测试剂（Oxidative Stress Detection Reagent）为非荧光、细胞可渗透的总ROS检测染料，能直接与多种活性氧物种反应，如过氧化氢、过氧亚硝酸盐和羟基自由基，生成绿色荧光产物，指示不同类型的ROS/RNS产生。此探针对超氧化物、活性氯或溴物种相对不敏感。
产品亮点
1、精准检测，双管齐下：该套件同时提供绿色荧光的氧化应激检测试剂与红色荧光的缺氧检测试剂，分别对应细胞内ROS水平与缺氧环境，实现精准定位与定量。
2、广泛适用，兼容性强：无论是贴壁细胞还是悬浮细胞，无论是采用荧光显微镜还是流式细胞仪，ROS-ID®套件都能灵活适应，满足您多样化的实验需求。两种规格（ENZ-51042-K500与ENZ-51042-0125）量身定制，灵活选择，经济高效。
3、操作简便，效率提升：我们对ROS-ID® Hypoxia/Oxidative Stress Detection Mix的准备过程进行了优化，确保实验准备简单快捷，减少实验误差，提升整体研究效率。
4、结果可视化，直观可信：实验设计包含正负对照，确保每次实验都有基准参考，使您的研究结论更具说服力。荧光信号直观显示，细胞状态一目了然，便于数据分析与解读。
结果分享：
