Enzo Life Sciences的MITO-ID® Membrane potential cytotoxicity kit利用陽離子雙發射染料檢測線粒體膜電位（MMP）的波動，該染料在細胞質中以綠色熒光單體的形式存在，在線粒體中以橙色熒光J聚集體的形式聚集。具有低膜電位的線粒體將積累低濃度的染料并呈現綠色熒光，而更高度極化的線粒體將呈現橙紅色熒光。隨著線粒體功能受損加劇，細胞表現出從橙色熒光到綠色熒光的轉變。該試劑盒是一種獨-特的HTS測定法，無需洗滌或去除培養基即可實時監測線粒體膜電位。

產品特點

● 靈敏度是JC-1熒光染料的10倍，并具有卓-越的水溶性

● 具備光穩定性的雙發射染料

● 無需漂洗/換液步驟

● 單獨的MITO-ID®檢測可用于檢測線粒體質量

● 可在較低的藥物/劑量濃度下檢測細胞毒性

● 沒有使用JC-1染料時出現的溶劑偽影

● 適用于高通量應用

實驗示例

圖1. 檢測線粒體紊亂的靈敏度是JC-1的10倍。使用MITO-ID®膜電位染料（紅色）或JC-1（藍色）在經CCCP處理的HeLa細胞中評估線粒體膜電位（MMP）。使用傳統的熒光酶標儀檢測，結果顯示MMP 隨著CCCP濃度的增加而減少，橙色熒光減少。染料的水溶性優化和無需洗滌的實驗方案最大限度減小了可變性，因此Z因子（>0.9）高于使用JC-1.

圖2. 在藥物篩選中實時檢測有絲分裂毒性。使用BioTek Synergy™ Mx熒光酶標儀對線粒體膜電位變化的時間進程研究。HeLa細胞與MITO-ID®膜電位染料在室溫下孵育30分鐘（不去除血清或培養基）。添加魚藤酮分別達到1µM、3µM和9µM的濃度。橙色信號的減少證明染料對魚藤酮有反應。
