Product Summary for Human VEGFR2/KDR Quantikine ELISA Kit
The Quantikine Human VEGF R2 Immunoassay is a 4.5 hour solid-phase Immunoassay designed to measure human soluble VEGF R2 in cell culture supernates, cell lysates, serum, and plasma. It contains NS0-expressed recombinant human VEGF R2/Fc Chimera and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human VEGF R2 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 soluble VEGF R2.

Recovery for Human VEGFR2/KDR Quantikine ELISA Kit
The recovery of VEGF R2 spiked to levels throughout the range of the assay was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 99 | 92-104 |
Linearity
To assess the linearity of the assay, samples containing high concentrations of VEGF R2 were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
