Product Summary for Human SCF Quantikine ELISA Kit
The Quantikine Human SCF Immunoassay is a 4.5 hour solid phase ELISA designed to measure SCF levels in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant human soluble SCF (KL-1 variant) and antibodies raised against this recombinant factor. Results obtained for naturally occurring human SCF samples 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 SCF.

Recovery for Human SCF Quantikine ELISA Kit
The recovery of SCF spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=2) | 85 | 75-93 |
| Citrate Plasma (n=8) | 94 | 84-112 |
| EDTA Plasma (n=8) | 98 | 82-110 |
| Heparin Plasma (n=8) | 99 | 88-116 |
| Serum (n=8) | 99 | 87-111 |
Linearity
To assess the linearity of the assay, the following biological samples were diluted with the appropriate Calibrator Diluent and then assayed. The cell culture media was spiked with exogenous SCF.
