Product Summary for Human sE-Selectin/CD62E Quantikine ELISA Kit
The Quantikine Human sE-Selectin immunoassay is a 4.5 hour solid phase ELISA designed to measure sE-Selectin in cell culture supernates, serum, and plasma. It contains CHO cell-expressed recombinant human sE-Selectin and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human sE-Selectin 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 sE-Selectin.

Recovery for Human sE-Selectin/CD62E Quantikine ELISA Kit
The recovery of sE-Selectin spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 103 | 98-110 |
| Citrate Plasma (n=4) | 96 | 85-107 |
| Heparin Plasma (n=4) | 94 | 85-107 |
| Serum (n=4) | 96 | 85-106 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of sE-Selectin were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
