自由基和其他活性种在许多心理和病理生理过程中发挥着重要作用。自由基一旦在细胞内产生,就会破坏多种细胞成分,包括蛋白质、脂质和DNA。然而,在较低浓度下,自由基可以作为细胞信号传导中的第二信使。
Enzo Life Sciences的ROS-ID??ROS/RNS detection kit可用荧光显微镜直接实时监测活细胞中活性氧与活性氮(ROS/RNS)的产生。该试剂盒中包含三种检测探针:NO检测试剂(红色,Ex/Em 650/670 nm),用于总ROS检测的氧化应激检测试剂(绿色,Ex/Em 490/525 nm)和超氧化物检测试剂(橙色,Ex/Em 550/620 nm)。试剂盒内还包括阳性对照,绿脓菌素和L-精氨酸,它们分别是ROS和NO产生的常见诱导剂;阴性对照N-乙酰-L-半胱氨酸和c-PTIO则分别是ROS和NO的常见清除剂。通过将三种检测探针与一组特异性抑制剂、激活剂相结合,能够区分超氧化物、一氧化氮和过氧亚硝酸盐。

实验示例
图1. 氧化应激检测试剂(绿色)、超氧化物检测试剂(蓝色)和NO检测试剂(红色)的激发和发射光谱。
图2. 使用ROS/RNS检测试剂盒演示HeLa细胞中过氧亚硝酸盐和NO生成的代表性实验。分析表明,由于NO与超氧化物的反应,L-精氨酸和绿脓菌素的联合处理产生过氧亚硝酸盐(绿色荧光),但很少产生NO(红色荧光)。
