Abstract
By using a potential-dependent J-aggregate-forming delocalized lipophilic cation, 5,5',6,6'-tetrachloro-1,1',3,3'-tetraethylbenzimidazolocarbocyanine++ + iodide (JC-1), we find that membrane potentials across mitochondria in a living cell can be heterogeneous. Remarkably, even within a long contiguous mitochondrion, regional heterogeneity in membrane potentials appears to be possible.
摘要
通过使用一种电位依赖性J-聚集体形成的离域亲脂性阳离子，5,5',6,6'-四氯-1,1',3,3'-四乙基苯并咪唑碳菁碘化物（JC-1），我们发现活细胞中线粒体的跨膜电位可能是异质性的。值得注意的是，即使在一个长的连续线粒体中，膜电位的区域异质性似乎也是可能的。
