74586-9
LaboratoryCoenzyme Q cytochrome C reductase (Complex III) [Enzymatic activity/mass] in Tissue
Definition
Determination of complex III activity by spectroscopy at 550 nm quantification. Complex III transfers electrons from ubiquinol or CoQ10 towards cytochrome c. The activity is inhibited by antimicina. It measures the increase in absorbance at 550 nm wavelength of the reduced cytochrome c. The final activity was calculated using the difference between the activity measured with and without antimicina.
