Detection Principle
ATPase catalyzes the hydrolysis of adenosine triphosphate (ATP) to adenosine diphosphate (ADP) and inorganic phosphorus. The activity of ATPase was determined by inorganic phosphorus production per unit time.

Technical Data:
Parameter:
Intra-assay Precision
Three human serum 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) | 0.85 | 1.36 | 2.25 |
| %CV | 4.4 | 3.8 | 3.8 |
Inter-assay Precision
Three human serum 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) | 0.85 | 1.36 | 2.25 |
| %CV | 4.6 | 5.2 | 5.2 |
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 95%.
| Standard 1 | Standard 2 | Standard 3 | |
| Expected Conc. (mmol/L) | 0.015 | 0.04 | 0.075 |
| Observed Conc. (mmol/L) | 0.0 | 0.0 | 0.1 |
| Recovery rate(%) | 96 | 98 | 91 |
Sensitivity
The analytical sensitivity of the assay is 0.06 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.
Standard Curve
As the OD value of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique or temperature effects), so the standard curve and data are provided as below for reference only:
| Concentration (mmol/L) | 0 | 0.01 | 0.02 | 0.03 | 0.05 | 0.06 | 0.08 | 0.10 |
| Average OD | 0.048 | 0.092 | 0.148 | 0.209 | 0.322 | 0.382 | 0.494 | 0.580 |
| Absoluted OD | 0 | 0.045 | 0.100 | 0.161 | 0.275 | 0.334 | 0.447 | 0.540 |
