Product Summary for Human CD117/c-kit Quantikine ELISA Kit
The Quantikine Human SCF sR Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human SCF sR in cell culture supernates, serum, and plasma. It contains Sf 21-expressed recombinant human SCF sR and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human SCF sR 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 SCF sR.

Recovery for Human CD117/c-kit Quantikine ELISA Kit
The recovery of SCF sR 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 | 97-110 |
| EDTA Plasma (n=4) | 91 | 84-106 |
| Heparin Plasma (n=4) | 92 | 87-102 |
| Serum (n=4) | 93 | 86-115 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of SCF sR were serially diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.
