JC-1 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. JC-1 fluorescence is usually excited by the 488?nm laser wavelength common in flow cytometers. JC-1 (2.5?μM) exposed to murine L1210 lymphoblasts, can be detected the presence of both cytoplasmic JC-1 monomer and mitochondrial J-aggregates in these cells.

A tetraiodofluorescein used as a red coloring in some foods (cherries, fish), as a disclosure of DENTAL PLAQUE, and as a stain of some cell types. It has structural similarity to THYROXINE.

2-Di-1-ASP is a mono-stryryl dye and widely used as mitochondrial stain and groove-binding fluorescent probes for double-stranded DNA.
