Description	Rhodamine 123 is a fluorescent dye (λex=503 nm, λem=527 nm).
Related Catalog	Signaling Pathways >> Others >> Others Research Areas >> Cardiovascular Disease Dye Reagents
In Vitro	The intensity of R123 fluorescence has a peak at concentration of 50 μM, and decreases to zero at higher concentrations due to self-quenching[1].
Kinase Assay	Measurements are made at room temperature with continuous stirring of the mitochondrial suspension using spectrophotometer equipped with a magnetic stirrer with fluorescent cation R123 as probe. Excitation and emission wavelengths are 503 nm and 527 nm, respectively. The incubation medium is the respiration buffer. R123 and sodium pyruvate are added to final concentrations of 50 nM and 10 mM, respectively. Isolated mitochondria maintain a steady membrane potential (±5%) throughout the duration of the recording[1].
