Detection Principle
Coenzyme Q, the catalytic product of mitochondrial complex II, can further reduce 2, 6-dichloroindoxol, which has a characteristic absorption peak at 600 nm. Therefore, the activity of mitochondrial complex II can be quantified by measure the change OD value at 600 nm.

Parameter:
Intra-assay Precision
Three rat heart tissue samples were assayed in replicates of 20 to determine precision within an assay. (CV = Coefficient of Variation)
| Parameters | Sample 1 | Sample 2 | Sample 3 |
| Mean (U/L) | 2.35 | 12.60 | 15.50 |
| %CV | 4.3 | 3.8 | 3.9 |
Inter-assay Precision
Three rat heart tissue samples were assayed 20 times in duplicate by three operators to determine precision between assays.
| Parameters | Sample 1 | Sample 2 | Sample 3 |
| Mean (U/L) | 2.35 | 12.60 | 15.50 |
| %CV | 4.9 | 5.2 | 4.9 |
Recovery
Take three samples of high concentration, middle concentration and low concentration to test the samples of each concentration for 6 times parallelly to get the average recovery rate of 97%.
| Sample 1 | Sample 2 | Sample 3 | |
| Expected Conc. (μmol/L) | 4.5 | 9.8 | 14.5 |
| Observed Conc. (μmol/L) | 4.5 | 9.6 | 13.3 |
| Recovery rate (%) | 101 | 98 | 92 |
Sensitivity
The analytical sensitivity of the assay is 0.54 U/L. This was determined by adding two standard deviations to the mean O.D. obtained when the zero standard was assayed 20 times, and calculating the corresponding concentration.
