Technical Data:
Parameter:
Intra-assay Precision
Three rat brain 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 (μmol/L) | 8.50 | 34.60 | 70.50 |
| %CV | 5.1 | 5.0 | 4.9 |
Inter-assay Precision
Three rat brain tissue samples were assayed 20 times in duplicate by three operators to determine precision between assays.
| Parameters | Sample 1 | Sample 2 | Sample 3 |
| Mean (μmol/L) | 8.50 | 34.60 | 70.50 |
| %CV | 9.8 | 9.1 | 9.6 |
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 104%.
| Sample 1 | Sample 2 | Sample 3 | |
| Expected Conc. (μmol/L) | 18.5 | 42.7 | 65.1 |
| Observed Conc. (μmol/L) | 18.7 | 44.8 | 69.0 |
| Recovery rate (%) | 101 | 105 | 106 |
Sensitivity
The analytical sensitivity of the assay is 3.0 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.
