Enzo Life Sciences的ROS-ID® Total ROS/Superoxide detection kit包括兩種熒光染料作為主要成分：非熒光、可滲透細(xì)胞的氧化應(yīng)激檢測(cè)試劑（綠色，Ex/Em 490/525 nm）與多種活性物質(zhì)（過(guò)氧化氫、過(guò)氧亞硝酸根和羥基）直接反應(yīng)，產(chǎn)生綠色熒光產(chǎn)物。超氧化物檢測(cè)試劑（橙色，Ex/Em 550/620 nm）是一種可滲透細(xì)胞的探針，可與超氧化物特異性反應(yīng)，產(chǎn)生橙色熒光產(chǎn)物。試劑盒還提供Pycyanin（ROS誘導(dǎo)劑）和NAC（ROS抑制劑）。

產(chǎn)品特點(diǎn)

● 用于檢測(cè)活細(xì)胞中超氧化物的產(chǎn)生

● 與細(xì)胞培養(yǎng)基的主要成分（酚紅，F(xiàn)BS和BSA）兼容

● 已通過(guò)顯微鏡、流式細(xì)胞儀和微孔板等應(yīng)用驗(yàn)證

實(shí)驗(yàn)示例

圖1. 在加入了ROS/超氧化物檢測(cè)試劑并用綠膿菌素處理的 HeLa 細(xì)胞中，通過(guò)熒光顯微鏡對(duì)活性氧的形成進(jìn)行了分析。在綠色通道中監(jiān)測(cè)一般氧化應(yīng)激水平，而在橙色通道中檢測(cè)超氧化物的產(chǎn)生。用 NAC（一種通用的 ROS 抑制劑）預(yù)處理可防止 ROS 的形成。

圖2. 使用ROS-ID® Total ROS/Superoxide detection kit和ROS清除劑/抑制劑分析用抗-霉-素A（AMA，特異性超氧化物誘導(dǎo)劑）、叔丁基-過(guò)氧化物（TBHP，特異性過(guò)氧化物誘導(dǎo)劑）和綠膿菌素（通用ROS誘導(dǎo)劑）處理的HeLa細(xì)胞中ROS的產(chǎn)生。使用U-2 OS和CHO K1細(xì)胞獲得了類似的結(jié)果。

圖3. 通過(guò)流式細(xì)胞術(shù)分析Hela細(xì)胞中ROS的形成。數(shù)據(jù)以綠膿菌素（ROS/SO誘導(dǎo)劑）、TBHP（ROS 誘導(dǎo)劑）和 AMA（超氧化物誘導(dǎo)劑）處理后的陽(yáng)性百分比表示。綠色柱表示ROS 陽(yáng)性率%，橙色柱表示超氧化物陽(yáng)性率%。
