Product Overview :
Significance of Measurement: Mitochondrial complex IV, also known as cytochrome c oxidase, catalyzes the oxidation of reduced cytochrome c and transfers electrons to oxygen to form water. It is a key component of the mitochondrial electron transport chain.
Principle of Measurement: Reduced cytochrome c exhibits a characteristic absorption peak at 550 nm. The decrease in absorbance at 550 nm reflects mitochondrial complex IV activity.
