A donor rat (n = 1) was used to isolate syngeneic mitochondria from the pectoralis major muscle tissue as … Rhodamine 6G has been employed to study microvascular reperfusion injury and the stimulation and inhibition of F 1-ATPase from the thermophilic bacterium PS3. In brief, 2-(4-diethylamino-2-hydroxybenzoyl)benzoic acid (1; 1.50 g, … Isolated plasma membranes (30 μg of protein) were resuspended in 1 ml of transport buffer [50 mM Hepes (pH 7.0), 5 mM MgCl 2 , 150 nM R6G, and 10 mM azide] and incubated at 35°C. Cited in 2 publications Rhodamine 6G (R6G) is a fluorescent dye that binds tightly to the inner mitochondrial membrane and is a potent inhibitor of oxidative phosphorylation . The latter is a fluorescent probe, which accumulates specifically in mitochondria of whole cells and which is used extensively to visualize mitochondrial morphology. Several inner membrane proteins from rat liver mitochondria have been translated for the first time in rabbit reticulocyte lysates. This use relies on the fact that rhodamine 123 accumulates in membranes in a manner which is dependent on membrane polarization. for 5 days. Upon entering the cell, Rhodamine 6G binds to the inner membranes of mitochondria. On the 5th day after the last day of dye administration, the mice were killed and testicular tissue was prepared for electron microscopy. synthesizing a rhodamine intermediate, then incorporating the S atom into the spirocyclic structure, and finally linking the mitochondrial-targeting moiety of triphenylphosphonium cation to the skeleton of rhodamine thiolactone. Cell membrane staining showed that F-18-labeled rhodamines did not accumulate in the cell membrane, as might be seen for a non-specific, lipophilic dye. Rhodamine 6G , … The objective of this study was to develop an experimental and computational approach for estimating ΔΨ m in intact rat lungs using the lipophilic fluorescent cationic dye rhodamine 6G (R6G). Rhodamine 6G inhibited ATP hydrolysis by oligomycin-sensitive ATPase, purified from rat liver mitochondria, in good accord with the dose-response curve for its inhibition of energy transduction of ATP synthesis in mitochondria, but it did not inhibit ATP hydrolysis by purified F1. Rhodamine B, hexyl ester, perchlorate (R 6) is a cell-permeant, cationic, orange-red fluorescent dye that is readily sequestered by active mitochondria with excitation/emission maxima ~528/551 nm. & Nelson, B.D.

In vitro processing, catalyzed by the isolated matrix fraction, is inhibited by rhodamine 6G. Based on these observations, it has been proposed that Rhodamine dyes may be used for producing fluorescent images of mitochondria with low background noise and high resolution. The lipophilic dye, rhodamine 6G, has been shown to be a potent inhibitor of oxidative phosphorylation, with a Ki of about 3 µm, corresponding to 1.2 … In a separate set of experiments, ZDF rats (n = 4) were used for visualization of mitochondrial uptake in the heart. It has been used to remove the mitochondrial influence from one parent cell line prior to construction of cybrids or hybrids using hamster and mouse cells. Cationic rhodamines (Rh 123 and Rh 6G) can cause developmental toxicity in mice and inhibit embryonic mitochondrial respiration following in vivo or in vitro dye exposure. , using a Fluorolog II fluorescence spectrometer (Horiba) ( 7 ). by isolated liver mitochondria or by the isolated mitochondrial matrix fraction. Rhodamine 6G, CAS: 989-38-8, is A rhodamine analog potentially useful in Pgp efflux assays. When either mutant is treated with low levels of rhodamine 6G, mitochondrial associated fluorescence is significantly lower than in wild type cells. MSC CM taken from rhodamine 6G–pretreated MSCs with dysfunctional mitochondria were unable to affect these parameters . The novel action of rhodamine 6G reported here can form the basis for its inhibition of precursor processing in intact hepatoma cells [Kolarov, J. It can be used in characterizing the kinetics of MRP1- mediated efflux, and as a laser dye and potential mitochondrial probe. low 10 PM rhodamine 6G, no mitochondrial swelling, loss of matrix protein, or endogenous I(+, Cazf, or Mg2+, was ob- served. Uptake of the F-18--labeled rhodamines was rapid (< 2 min) and no washout was observed. It can be used in characterizing the kinetics of MRP1- mediated efflux, and as a laser dye and potential mitochondrial probe. The laser dye rhodamine 123 is also used in ...Rhodamine dyes fluoresce and can thus be detected easily and inexpensively with instruments called fluorometers. Exposure to excitation light for a few minutes diffused the mitochondria-staining dye (6G or 123) into the cytoplasm, so that the outline of the fluorescent mitochondria Rhodamine 6G inhibits matrix-catalyzed processing of all precursors tested, indicating that the mechanism of inhibition is common for a variety of functionally unrelated precursors. 144, 387-392]. Rhodamine 6G, also known as Rhodamine 590, is widely used as a lasing medium and as a fluorescence tracer. Transformed Mitochondria Monitored by Rhodamine 529 concentration (data not shown). It has also been used to label platelets. Rhodamine 6G, an analog of rhodamine 123 (also positively charged and ... brane potential of mitochondria with the use of rhodamine 123 appears quite doubtful. These findings are in line with previous reports of improved bioenergetics in cells receiving MSC mitochondria, including macrophages, alveolar epithelial cells, and vascular endothelial cells ( 9 , 18 , 19 , 24 , 54 ). (1984) Eur. Mitochondrial membrane potential ( ΔΨ m ) plays a key role in vital mitochondrial functions, and its dissipation is a hallmark of mitochondrial dysfunction. ...Rhodamine dyes are generally toxic, and are soluble in water, methanol and ethanol. Rhodamine 6G is a fluorescent dye capable of penetrating a living cell. These … Rhodamine /ˈroʊdəmiːn/ is a family of related chemical compounds, fluorone dyes. At low concentrations, certain lipophilic rhodamine dyes selectively stain mitochondria in live cells. J. Biochem. d −1 i.p.
