A fast kinetic method for assessing mitochondrial membrane potential in isolated hepatocytes with rhodamine 123 and flow cytometry, Abstract, Rhodamine 123 (Rh123) is widely used as a flow cytometric probe for mitochondrial membrane potential (MMP) in metabolic, pharmacologic, and toxicological studies. Fluorescent dye most commonly used in flow cytometry as functional reporter for Pgp. It is utilized forstaining a wide variety of cells, including plant cells and bacteria. Rhodamine dyes fluoresce and can thus be detected easily and inexpensively with instruments called fluorometers. Functional assays for multi-drug resistance (MDR) proteins are better prognostic indicators in cancer . Mitochondrial energization induces quenching of RH-123 fluorescence and the rate of fluorescence decay is proportional to the mitochondrial membrane potential. Loss of potential will result in loss of the dye and, therefore, the fluorescence intensity. Rhodamine 123 is useful as a laser dye and to have selective cell growth effects.

The results indicate that at an appropriate dyetocell ratio (in our experiments, 50 g Rh123/ml for 250,000-300,000 cells/ml), the initial rate of Rh123 uptake is a highly reproducible and sensitive parameter for estimation of MMP, as demonstrated by the effects of substrates and inhibitors of the glycolytic pathway and mitochondrial respiration. mitochondrial membrane potential and sperm maturity (Ortega Ferrusola et al., 2017). It is widely used in flow cytometry studies involving mitochondrial membrane potential. Positively charged rhodamine dyes (such as rhodamine esters and rosamines) are selectively localized in mitochondria, thus they are widelyused for labeling mitochondria of live cells. Rhodamine 123 (RH-123) was used to monitor the membrane potential of mitochondria isolated from rat liver.

MitoTracker is a commercially available fluorescent dye (Invitrogen/Molecular Probes) that, like the aforementioned dyes, labels mitochondria within live cells utilizing the mitochondrial membrane potential. Cationic fluorescent dyes are commonly used tools to assess MMP. During this apoptosis assay, cells are stained with Rhodamine 123 or TMRE and excess dye is removed by washing. Decreases in mitochondrial membrane potential (MMP) have been associated with mitochondrial dysfunction that could lead to cell death. BioAssay record AID 1776697 submitted by ChEMBL: Induction of mitochondrial membrane potential loss in human HT-29 cells assessed as fluorescence intensity at IC50 concentration measured after 72 hrs by rhodamine 123 staining based FACScan flow cytometry.

In summary, our findings suggest that cocaine toxicity was due to loss of mitochondrial membrane potential, vacuolation, and dual inhibition of cell cycle phases. Rhodamine 123-labeled mitochondrial membrane potential assay by flow cytometry. With respect to apoptosis, the presence of mitochondrial membrane potential can be probed with rhodamine 123 while the structure and integrity of mitochondria can be assessed . It uses the red-fluorescent probe TMRM (tetramethylrhodamine, methyl ester) that localizes in mitochondria . Appendix 4: Glossary Mitochondrial membrane potential (Dy) is generated by mitochondrial electron transport chain, which drives a proton flow from matrix through inner mitochondrial membrane to cytoplasm, thus creating an electrochemical gradient.This gradient is in turn responsible for the formation of ATP molecules by F 0-F 1 ATP synthase. For this reason Dy is an important parameter for . The dye distributes according to the negative potential of the membrane. Yeast cells were cultivated in YPD liquid medium overnight and a secondary culture was grown in YPG liquid medium until the log phase after being washed by a sterile PBS buffer. All Photos (3) R8004.
