Product Summary for Human CD40 Ligand/TNFSF5 Quantikine ELISA Kit
The Quantikine Human CD40 Ligand Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human CD40 Ligand in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant human CD40 Ligand and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human CD40 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 naturally occurring human CD40 Ligand.

Recovery for Human CD40 Ligand/TNFSF5 Quantikine ELISA Kit
The recovery of CD40 Ligand spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 102 | 90-114 |
| Platelet-poor EDTA Plasma (n=5) | 98 | 86-107 |
| Platelet-poor Heparin Plasma (n=5) | 94 | 86-113 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of CD40 Ligand were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
