There are some fluorescent dyes available which you can use for mitochondrial potential measurement. We have developed a novel strategy to identify higher productivity cells at the FACS step by leveraging a simple viable cell staining method that detects mitochondrial membrane potential On this page: Because the fractional loss of dye from the extracellular medium in Fig. Increased ATP generation or mitochondrial dysfunction can lead to a decrease in mitochondrial membrane potential (Suski et al., 2012; Logan et al., 2016). JC-1 Mitochondrial Membrane Potential Assay kits comprise lipophilic cationic fluorescent dye; 5,5,6,6-tetrachloro-1,1,3,3-tetraethylbenzimi-dazoylcarbocyanine iodide (JC-1). Like JC-10, TMRE and TMRM uptake in mitochondria is driven by the mitochondrial membrane potential. MitoProbe DiIC1(5) Mitochondrial Membrane Potential Protocol | Thermo Fisher Scientific - CAS Number: 3520-43-2. Purity: Why do mitochondria have double membrane? The double membrane comes from the theory that the mitochondria arose as a symbiont. The outer membrane resembles a typical eukaryotic cell while the inner membrane has characteristics of a prokaryotic membrane . In non-apoptotic cells, JC-1 accumulates as aggregates in the 1995;260:406-17. doi: 10.1016/0076 To determine mitochondrial membrane potential after the addition of TA (30 M), GA (30 M), or EA (30 M) compounds during 6 days of osteoclast differentiation of RAW264.7 cells, staining was performed using JC-1 dye. Mitochondrial uptake of the cationic fluorescent dye, rhodamine 123, has been used for the estimation of mitochondrial membrane potential. The Mitochondrion Contains an Outer Membrane, an Inner Membrane, and Two Internal Compartments. Each mitochondrion is bounded by two highly specialized membranes, which have very different functions. Together they create two separate mitochondrial compartments: the internal matrix and a much narrower intermembrane space. The cationic hydrophobic mitochondrial potential dye accumulates in normal mitochondria, most likely due to the mitochondrial potential, resulting in an increase in fluorescence (em = 535 nm). JC-1 is more advantageous over rhodamines and other carbocyanines, capable of entering selectively into mitochondria, since it changes reversibly its color from green to orange as membrane potentials increase (over values of about 80-100 mV). Measurement of Mitochondrial Membrane Potential with the Fluorescent Dye Tetramethylrhodamine Methyl Ester (TMRM) The mitochondrial membrane potential Since these mitochondrial attributes are dynamic, simultaneous analysis using multiple staining in a single sample is required.
