ROS-ID®缺氧/氧化应激检测试剂盒——ENZO热销产品

更新时间:2023-11-16   点击次数:165次

Enzo Life SciencesROS-ID®Hypoxia/Oxidative stress detection kit专门用于使用荧光显微镜或流式细胞对活细胞(悬浮和贴壁)中的缺氧和氧化应激水平进行功能性检测。该试剂盒包含能够检测缺氧状态(红色)和氧化应激水平(绿色)的荧光探针。

检测缺氧的染料(红色)利用缺氧细胞中存在的硝基还原酶活性,将硝基基团转化为羟胺(NHOH)和氨基(NH2)并释放出荧光探针。


氧化应激检测试剂(绿色)是一种非荧光的、可透过细胞的总ROS检测染料,可与多种活性物质直接反应。可使用配备标准荧光素(490/525 nm)和德克萨斯红(596/670 nm)滤光片的宽场荧光显微镜、共聚焦显微镜或配备蓝色(488 nm)激光的流式细胞仪进行细胞分析。

 

产品特点

● 高灵敏度和特异性的荧光探针,可用于检测活细胞的缺氧和氧化应激

● 可用于分析贴壁或悬浮细胞系

● 试剂盒内包含整套试剂,包括ROS和缺氧诱导剂
