Product Summary for Human Complement Factor D Quantikine ELISA Kit
The Quantikine Human Complement Factor D Immunoassay is a 3.5 hour sandwich ELISA designed to measure human Complement Factor D in cell culture supernates, serum, plasma, and urine. It contains NS0-expressed recombinant human Complement Factor D and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human Complement Factor D 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 Complement Factor D.

Recovery for Human Complement Factor D Quantikine ELISA Kit
The recovery of Complement Factor D spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 104 | 97-117 |
| Urine (n=4) | 100 | 87-115 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of Complement Factor D were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
