Product Summary for Human Axl Quantikine ELISA Kit
The Quantikine® Human Axl Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human Axl in cell culture supernates, cell lysates, cerebrospinal fluid, serum, plasma, saliva, and urine. It contains
NS0-expressed recombinant human Axl and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human Axl 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 Axl.

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.

Recovery for Human Axl Quantikine ELISA Kit
The recovery of human Axl spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 89 | 81-98 |
| Cell Lysis Buffer (n=1) | 90 | 88-93 |
| Saliva (n=4) | 94 | 82-101 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of human Axl were diluted with calibrator diluent to produce samples with values within the dynamic range of the assay.
