线粒体膜电位(Mitochondrial Membrane Potential,MMP)是判定细胞健康程度、线粒体膜通透性和细胞凋亡的一个重要指标,MMP的丧失通常与细胞凋亡的早期阶段有关。评估线粒体功能状态的基于细胞的检测方法正在成为阐明线粒体活动在药物诱导毒性、细胞凋亡级联以及其他细胞和生化过程中的作用的有用工具。

Enzo Life SciencesMITO-ID® Membrane potential detection kit包含一种双发射阳离子染料,用于检测活细胞中的线粒体膜电位(MMP)。在有能量或活跃的细胞中,MITO-ID® 膜电位试剂因其相对负电荷而在线粒体中迅速聚集成发橙色荧光的聚合体,而在细胞质中则以发绿色荧光的单体存在。然而,在MMP受损的细胞中,MITO-ID®膜电位试剂主要以绿色荧光单体存在于整个细胞质中,在线粒体中不再表现出橙色荧光。

 

作用机制

该染料的基本化学结构由高度共轭的部分组成,使正电荷广泛离域。该染料能够选择性地进入线粒体,当膜电位增加时,它的颜色会从绿色可逆地变为橙色(双发射电位探针)。这种光物理特性是由于在膜极化时可逆地形成J-聚集体,导致在490nm处激发时,发射光从~530nm转移到590nm。因此,具有低膜电位的线粒体将积累低浓度的染料,并表现出绿色荧光,而更高极化的线粒体将表现出橙色的荧光。

实验示例

MITO-ID®线粒体膜电位检测试剂盒——ENZO热销产品

1. 检测线粒体紊乱的灵敏度是JC-110倍。使用MITO-ID®膜电位染料(红色)或JC-1(蓝色)在经CCCP处理的HeLa细胞中评估线粒体膜电位(MMP)。使用传统的荧光酶标仪检测,结果显示MMP 随着CCCP浓度的增加而减少,橙色荧光减少。染料的水溶性优化和无需洗涤的实验方案最大限度减小了可变性,因此Z因子(>0.9)高于使用JC-1.
