線粒體膜電位（Mitochondrial Membrane Potential,MMP）是判定細胞健康程度、線粒體膜通透性和細胞凋亡的一個重要指標，MMP的喪失通常與細胞凋亡的早期階段有關(guān)。評估線粒體功能狀態(tài)的基于細胞的檢測方法正在成為闡明線粒體活動在藥物誘導毒性、細胞凋亡級聯(lián)以及其他細胞和生化過程中的作用的有用工具。

Enzo Life Sciences的MITO-ID^??Membrane potential detection kit包含一種雙發(fā)射陽離子染料，用于檢測活細胞中的線粒體膜電位（MMP）。在有能量或活躍的細胞中，MITO-ID^??膜電位試劑因其相對負電荷而在線粒體中迅速聚集成發(fā)橙色熒光的聚合體，而在細胞質(zhì)中則以發(fā)綠色熒光的單體存在。然而，在MMP受損的細胞中，MITO-ID?膜電位試劑主要以綠色熒光單體存在于整個細胞質(zhì)中，在線粒體中不再表現(xiàn)出橙色熒光。

作用機制

該染料的基本化學結(jié)構(gòu)由高度共軛的部分組成，使正電荷廣泛離域。該染料能夠選擇性地進入線粒體，當膜電位增加時，它的顏色會從綠色可逆地變?yōu)槌壬p發(fā)射電位探針）。這種光物理特性是由于在膜極化時可逆地形成J-聚集體，導致在490nm處激發(fā)時，發(fā)射光從～530nm轉(zhuǎn)移到590nm。因此，具有低膜電位的線粒體將積累低濃度的染料，并表現(xiàn)出綠色熒光，而更高極化的線粒體將表現(xiàn)出橙色的熒光。
