Cell Meter™ JC-10 Mitochondrion Membrane Potential Assay Kit
Optimized for Microplate Assays
Although JC-1 is widely used in many labs, its poor water solubility makes it hard to use for some applications. Even at 1 µM concentration, JC-1 tends to precipitate in aqueous buffer. JC-10 has been developed to be a superior alternative to JC-1 where high dye concentration is desired. Compared to JC-1, our JC-10 has much better water solubility. JC-10 is capable of entering selectively into mitochondria, and changes reversibly its color from green to orange as membrane potentials increase. This property is due to the reversible formation of JC-10 aggregates upon membrane polarization that causes shifts in emitted light from 520 nm (i.e., emission of JC-10 monomeric form) to 570 nm (i.e., emission of J-aggregate). When excited at 490 nm, the color of JC-10 changes reversibly from green to greenish orange as the mitochondrial membrane becomes more polarized. This Cell Meter™ JC-10 Mitochondrial Membrane Potential Assay Kit enable you to monitor mitochondrial membrane potential changes using a simple microplate reader while all the other commercial JC-1 assay kits require the use of a flow cytometer. Our kit provides the most robust method to monitor mitochondrial membrane potential changes, and can be readily used for screening a large compound library.
Campotothecin-induced mitochondria membrane potential changes were measured with JC-10™ and JC-1 in Jurkat cells. After Jurkat cells were treated with camptothecin (10 µM) for 4 hours, JC-1 and JC-10™ dye working solutions were added to the wells and incubated for 30 minutes. The fluorescence intensities for both J-aggregates (highlighted in blue) and monomeric forms (highlighted in red) of JC-1 and JC-10™ were measured at Ex/Em = 490/525 nm (Cutoff = 515 nm) and 490/590 nm  (Cutoff = 570 nm) with NOVOstar microplate reader (BMG Labtech).
