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

Recovery for Human Fetuin A Quantikine ELISA Kit
The recovery of Fetuin A spiked to levels throughout the range of the assay was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 103 | 93-109 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of Fetuin A were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
