Dilution of Sample
The recommended dilution factor for different samples is as follows (for reference only):
| Sample type | Dilution factor |
| 10% Rat lung tissue homogenate | 1 |
| 10% Rat liver tissue homogenate | 1 |
| 10% Rat spleen tissue homogenate | 1 |
| 10% Rat kidney tissue homogenate | 1 |
| 10% Mouse lung tissue homogenate | 1 |
| 10% Mouse kidney tissue homogenate | 1 |
Note: The diluent is extracting solution. For the dilution of other sample types, please do pretest to confirm the dilution factor.
Detection Principle
Malate and NAD+ form oxoacetate and NADH under the action of malate dehydrogenase, then acetyl-coa and oxoacetate form coenzyme A and citrate under the action of citrate synthetase. The content of acetyl-coA can be calculated by measuring the change of absorbance value at 340 nm.

Parameter:
Intra-assay Precision
Three rat liver 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 (nmol/mL) | 225.00 | 348.00 | 405.00 |
| %CV | 4.4 | 4.0 | 3.6 |
Inter-assay Precision
Three rat liver tissue samples were assayed 20 times in duplicate by three operators to determine precision between assays.
| Parameters | Sample 1 | Sample 2 | Sample 3 |
| Mean (nmol/mL) | 225.00 | 348.00 | 405.00 |
| %CV | 5.0 | 5.2 | 5.7 |
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 103%.
| Sample 1 | Sample 2 | Sample 3 | |
| Expected Conc. (nmol/mL) | 185 | 279 | 452 |
| Observed Conc. (nmol/mL) | 192.4 | 287.4 | 461.0 |
| Recovery rate (%) | 104 | 103 | 102 |
Sensitivity
The analytical sensitivity of the assay is 150 nmol/mL. 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.
