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.

Biochem/physiol Actions

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.

Features and Benefits

  • 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
