Product Summary for Human Fas Ligand/TNFSF6 Quantikine ELISA Kit
The Quantikine® Human Fas Ligand/TNFSF6 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human Fas Ligand in cell culture supernates, cell lysates, serum, and plasma. It contains CHO cell-expressed recombinant human Fas Ligand and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human Fas Ligand 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 Fas Ligand.

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 using two lots of components.

Recovery for Human Fas Ligand/TNFSF6 Quantikine ELISA Kit
The recovery of human Fas Ligand spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Supernates (n=4) | 98 | 93-103 |
| EDTA Plasma (n=4) | 103 | 94-111 |
| Heparin Plasma (n=4) | 96 | 92-101 |
| Serum (n=4) | 101 | 96-103 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of human Fas Ligand were diluted with calibrator diluent to produce samples with values within the dynamic range of the assay.
