Product Summary for Human Amphiregulin Quantikine ELISA Kit
The Quantikine Human Amphiregulin Immunoassay is a 4.5 hour solid
phase ELISA designed to measure human Amphiregulin in cell culture
supernates, cell lysates serum, plasma, saliva, and urine. It contains E. coli-derived
recombinant human Amphiregulin and has been shown to accurately quantitate the recombinant factor.
Results obtained with natural human Amphiregulin showed
linear curves that were parallel to the standard curves obtained using
the Quantikine kit standards. These results indicate that this kit can
be used to determine relative mass values for natural human Amphiregulin.

Precision
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision. Assays were performed by at least three technicians using two lots of components.

Recovery for Human Amphiregulin Quantikine ELISA Kit
The recovery of Amphiregulin spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 95 | 88-101 |
| EDTA Plasma (n=4) | 93 | 82-105 |
| Heparin Plasma (n=4) | 94 | 82-103 |
| Saliva (n=4) | 104 | 98-113 |
| Serum (n=4) | 95 | 85-103 |
| Urine (n=4) | 88 | 75-99 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of human Amphiregulin were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
