Product Summary for Human P-Selectin/CD62P Quantikine ELISA Kit
The Quantikine® Human P-Selectin/CD62P Immunoassay is a 1.25 hour solid-phase ELISA designed to measure human P-Selectin in cell culture supernates, serum, and plasma. It contains recombinant human P-Selectin and antibodies raised against the recombinant factor. Results obtained using natural human P-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 natural human P-Selectin.

Sample Values
Serum/Plasma - Samples from apparently healthy volunteers were evaluated for the presence
of human P-Selectin in this assay. No medical histories were available for the donors used in
this study.

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 P-Selectin/CD62P Quantikine ELISA Kit
The recovery of Human P-Selectin spiked to three different levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 97 | 88-107 |
| Citrate Plasma (n=4) | 92 | 81-111 |
| EDTA Plasma (n=4) | 92 | 77-103 |
| Heparin Plasma (n=4) | 95 | 78-112 |
| Serum (n=4) | 93 | 77-104 |
Linearity
To assess the linearity of the assay, samples spiked with high concentrations of human P-Selectin were diluted with sample diluent to produce samples with values within the dynamic range of the assay. <br>
