Enzo Life Sciences的ROS-ID®Hypoxia/Oxidative stress detection kit專門用于使用熒光顯微鏡或流式細(xì)胞術(shù)對活細(xì)胞（懸浮和貼壁）中的缺氧和氧化應(yīng)激水平進(jìn)行功能性檢測。該試劑盒包含能夠檢測缺氧狀態(tài)（紅色）和氧化應(yīng)激水平（綠色）的熒光探針。

檢測缺氧的染料（紅色）利用缺氧細(xì)胞中存在的硝基還原酶活性，將硝基基團(tuán)轉(zhuǎn)化為羥胺（NHOH）和氨基（NH2）并釋放出熒光探針。

氧化應(yīng)激檢測試劑（綠色）是一種非熒光的、可透過細(xì)胞的總ROS檢測染料，可與多種活性物質(zhì)直接反應(yīng)?？墒褂门鋫錁?biāo)準(zhǔn)熒光素（490/525 nm）和德克薩斯紅（596/670 nm）濾光片的寬場熒光顯微鏡、共聚焦顯微鏡或配備藍(lán)色（488 nm）激光的流式細(xì)胞儀進(jìn)行細(xì)胞分析。

產(chǎn)品特點(diǎn)

● 高靈敏度和特異性的熒光探針，可用于檢測活細(xì)胞的缺氧和氧化應(yīng)激

● 可用于分析貼壁或懸浮細(xì)胞系

實(shí)驗(yàn)示例

圖1. 檢測人HeLa和HL-60細(xì)胞中的缺氧和氧化應(yīng)激水平。用缺氧誘導(dǎo)劑（DFO）和ROS誘導(dǎo)劑（pyocyanin）處理細(xì)胞。每個(gè)象限的數(shù)字反映了細(xì)胞（群體）的百分比。結(jié)果表明，缺氧和氧化應(yīng)激染料具有特異性。

圖2.使用不同試劑誘導(dǎo)HeLa細(xì)胞發(fā)生缺氧和氧化應(yīng)激反應(yīng)。缺氧探針在缺氧條件下被細(xì)胞硝基還原酶轉(zhuǎn)化后觀察到紅色熒光。

圖3.氧化應(yīng)激（A）和缺氧（B）檢測染料的吸收峰和發(fā)射峰分別為504nm/524nm和580nm/595nm。這些染料可以用488nm的氬離子激光器激發(fā)，并在流式細(xì)胞儀上的FL1通道（氧化應(yīng)激染料）和FL3通道（缺氧紅染料）中檢測。
