Product Summary for Human IL-19 Quantikine ELISA Kit
The Quantikine Human IL-19 immunoassay is a 4.5 hour solid phase ELISA designed to measure IL-19 in cell culture supernates, serum, plasma, saliva, urine, and human milk. It contains NS0-expressed recombinant human IL-19 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human IL-19 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 IL-19.

Recovery for Human IL-19 Quantikine ELISA Kit
The recovery of human IL-19 spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 98 | 93-104 |
| EDTA Plasma (n=4) | 94 | 85-102 |
| Heparin Plasma (n=4) | 93 | 87-99 |
| Serum (n=4) | 93 | 87-97 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of IL-19 were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
