Application

The Cytochrome c Oxidase Assay Kit uses an optimized colorimetric assay based on observation of the decrease in absorbance of ferrocytochrome c measured at 550 nm, which is caused by its oxidation to ferricytochrome c by cytochrome c oxidase. This kit is suitable for the detection of mitochondrial outer membrane integrity/mitochondrial stress and for the detection of mitochondria in subcellular fractions.

Actions biochimiques/physiologiques

Cytochrome c oxidase [EC 1.9.3.1] is located on the inner mitochondrial membrane dividing the mitochondrial matrix from the intermembrane space, and has traditionally been used as a marker for this membrane. It is also located in the cytoplasmic membrane of bacteria. Cytochrome c oxidase provides energy for the cell by coupling electron transport through the cytochrome chain with the process of oxidative phosphorylation.

Caractéristiques et avantages

  • Simple, optimized protocol - Obtain reproducible results without special training needs
  • Useful for determining cytochrome c activity from any mitchondrial source - The enzyme is present in all mitochondria regardless of species
  • Useful for detecting the presence of mitochondria in subcellular fraction - Save time and increase confidence in the quality of organelle preparations
  • May be used in conjunction with the MITOISO1 Mitochondrial Isolation Kit - Standardized mitochondrial preparation and analysis ensures reproducibility
  • Use to analyze the intactness of mitochondrial membranes
  • Simple colorimetric measurement of solution

Human primary myotubes are highly glycolytic when cultured in high glucose medium rendering it difficult to study mitochondrial dysfunction. Galactose is known to enhance mitochondrial metabolism and could be an excellent model to study mitochondrial dysfunction in human primary myotubes.

Nitrate, an inorganic anion abundant in vegetables, is converted in vivo to bioactive nitrogen oxides including NO. We recently demonstrated that dietary nitrate reduces oxygen cost during physical exercise, but the mechanism remains unknown. In a double-blind crossover trial we

Cells of the yeast Saccharomyces cerevisiae contain three NAD kinases; namely, cytosolic Utr1p, cytosolic Yef1p, and mitochondrial Pos5p. Previously, the NADH kinase reaction catalyzed by Pos5p, rather than the NAD kinase reaction followed by the NADP(+)-dependent dehydrogenase reaction, had been

Organelle Isolation

The isolation of subcellular fractions by centrifugation is a commonly used technique and is widely applicable across multiple cell and tissue types. Because organelles differ in their size, shape, and density, centrifugation can be easily employed to separate and purify organelle fractions from gently homogenized samples.
