| Description | JC-1 (CBIC2) is a fluorescent lipophilic carbocyanine dye. It has been used to measure mitochondrial membrane potential. JC 1 can be used in a probe for measuring mitochondrial membrane potential by flow cytometry. |
| In vitro | JC-1通常由流式细胞仪中常见的488nm激光波长激发[1]。在暴露于小鼠L1210淋巴母细胞的JC-1 (2.5μM)中，可以检测到这些细胞中细胞质中JC-1单体和线粒体J聚集体的存在。通过使用JC-1 (1 μg/mL, 15 min)对线粒体进行荧光标记，揭示了它们在星形胶质细胞内分布不均，导致线粒体含量高低不一的区域[2]。JC-1在敏感的K562细胞中积聚得较多，在这些细胞中表现出绿色的细胞质和红色的线粒体荧光。JC-1在耐药的K562细胞中积聚得较少，这些细胞仅显示出轻微的绿色荧光[4]。已显示JC-1与α-突触核蛋白在酸性C末端区域相互作用，其Kd为2.6μM。在没有铁的情况下，JC-1本身不会加速α-突触核蛋白的聚合过程，相反，它通过延长滞后期来减缓聚合过程[3]。 |
