Enzo Life Sciences：ROS-ID®總活性氧/超氧化物檢測試劑盒

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、可滲透細胞的氧化應激檢測試劑（綠色，Ex/Em 490/525 nm）與多種活性物質（過氧化氫、過氧亞硝酸根和羥基）直接反應，產生綠色熒光產物。超氧化物檢測試劑（橙色，Ex/Em 550/620 nm）是一種可滲透細胞的探針，可與超氧化物特異性反應，產生橙色熒光產物。試劑盒還提供Pycyanin（ROS誘導劑）和NAC（ROS抑制劑）。

產品特點

● 用于檢測活細胞中超氧化物的產生

● 與細胞培養基的主要成分（酚紅，FBS和BSA）兼容

● 已通過顯微鏡、流式細胞儀和微孔板等應用驗證

實驗示例

圖1. 在加入了ROS/超氧化物檢測試劑并用綠膿菌素處理的 HeLa 細胞中，通過熒光顯微鏡對活性氧的形成進行了分析。在綠色通道中監測一般氧化應激水平，而在橙色通道中檢測超氧化物的產生。用 NAC（一種通用的 ROS 抑制劑）預處理可防止 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劑）、叔丁基-過氧化物（TBHP，特異性過氧化物誘導劑）和綠膿菌素（通用ROS誘導劑）處理的HeLa細胞中ROS的產生。使用U-2 OS和CHO K1細胞獲得了類似的結果。

圖3. 通過流式細胞術分析Hela細胞中ROS的形成。數據以綠膿菌素（ROS/SO誘導劑）、TBHP（ROS 誘導劑）和 AMA（超氧化物誘導劑）處理后的陽性百分比表示。綠色柱表示ROS 陽性率%，橙色柱表示超氧化物陽性率%。
