Product Description

Sample Type: Cell culture Reagent Name: TMRE Target: Mitochondrial depolarization Excitation/Emission: 549nm/574nm Method of Analysis: Flow Cytometry, Fluorescence Microscope, Fluorescence Plate Reader Intended Use: The MitoPT TMRE BioAssay(TM) detects mitochondrial membrane depolarization utilizing the fluorescent dye TMRE. When accumulated in a negatively charge polarized mitochondria, TMRE fluoresces orange. When mitochondrial membrane potential collapses in apoptotic or metabolically stressed cells, TMRE reagent is dispersed through the cell cytosol and fluorescence levels drop dramatically. Analyze your results using a flow cytometer, fluorescence plate reader, or fluorescence microscopy. Test Principle: Loss of mitochondrial membrane potential is indicative of apoptosis. MitoPT TMRE Assay utilizes the potentiometric fluorescent dye TMRE to detect mitochondrial membrane permeability and membrane depolarization. The TMRE dye has a delocalized positive charge dispersed throughout its molecular structure. In addition, its lipophilic solubility enables it to be readily membrane permeant and penetrate living cells. The TMRE dye enters the negatively charge mitochondria where it accumulates and fluoresces orange upon excitation. When the mitochondrial membrane potential collapses in apoptotic cells, MitoPT TMRE becomes distributed throughout the cytosol. Detection of the loss of orange-red fluorescence in TMRE stained cells is a reliable method for assessing apoptosis induction or oxidative stress-induced mitochondrial depolarization in experimental cell populations.
