Product Summary for Human ENPP-2/Autotaxin Quantikine ELISA Kit
The Quantikine Human ENPP-2 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human ENPP-2 in cell culture supernates, serum, plasma, urine, and human milk. It contains NS0-expressed recombinant human ENPP-2 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human ENPP-2 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 ENPP-2.

Recovery for Human ENPP-2/Autotaxin Quantikine ELISA Kit
The recovery of ENPP-2 spiked to levels throughout the range of the assay was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 102 | 93-109 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of ENPP-2 were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
