Uses
JC-1 is commonly used to determine mitochondrial membrane potential. It is a cationic carbocyanine dye that is membrane permeable and is often used for flow cytometry and fluorescent microscopy. This dye changes color as the membrane potential increases. At higher potentials, JC-1 forms aggregates, which changes the fluorescence emission color from green to red. Dyes and metabolites.
Definition
ChEBI: 1,1',3,3'-tetraethyl-5,5',6,6'-tetrachloroimidacarbocyanine iodide is a cyanine dye and an organic iodide salt. It has a role as a fluorochrome. It contains a 1,1',3,3'-tetraethyl-5,5',6,6'-tetrachloroimidacarbocyanine.
General Description
A cationic, fluorescent, carbocyanine dye that can be used as a ratiometric indicator of mitochondrial potential ΔΨ
m in cells, tissues, and isolated mitochondria. It labels mitochondria with high membrane potential orange and mitochondria with low membrane potential green. Mitochondrial depolarization is indicated by a decrease in the red/green fluorescence intensity ratio. Ideal for detection of collapse of ΔΨ
m induced by uncouplers of mitochondrial respiration. The potential-sensitive color shift is due to concentration-dependent formation of red fluorescent J-aggregates. JC-1 has also been used in a functional assay of multidrug-resistance cells and in apoptosis-related mitochondrial modifications.
