TEST PRINCIPLE
| This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human ALPP. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human ALPP and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human ALPP, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Human ALPP. You can calculate the concentration of Human ALPP in the samples by comparing the OD of the samples to the standard curve. |

ASSAY PROCEDURES
TYPICAL DATA
Human ALPP ELISA Standard Curve
Typical data are for reference only and curves should be replotted for each experiment. The Logistics function is recommended for fitting.
PRECISION
Intra-Assay Precision (Precision within an assay): Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays): Three samples of known concentration were tested in twenty separate assays to assess inter-assay precision. Assays were performed by at least three technicians using two lots of components.

RECOVERY
The recovery of Human ALPP spiked to three different levels in samples throughout the range of the assay in various matrices was evaluated.
| Sample Type | Range (%) | Average Recovery (%) |
|---|---|---|
| Serum(n=8) | 90-101 | 95 |
| EDTA plasma (n=8) | 91-105 | 99 |
| Cell culture media (n=8) | 93-111 | 101 |
LINEARITY
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of Human ALPP in various matrices were diluted with the Reference Standard & Sample Diluent to produce samples with values within the dynamic range of the assay.
