Product Summary for Human IL-5 Quantikine ELISA Kit
The Quantikine Human IL-5 Immunoassay is a 4.5 hour solid phase ELISA designed to measure IL-5 levels in cell culture supernates, serum, plasma, and urine. It contains Sf 21-expressed recombinant human IL-5 and antibodies raised against the recombinant factor and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human IL-5 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 IL-5.

Recovery for Human IL-5 Quantikine ELISA Kit
The recovery of human IL-5 spiked to different levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 101 | 95-107 |
| EDTA Plasma (n=4) | 104 | 86-118 |
| Heparin Plasma (n=4) | 101 | 87-112 |
| Serum (n=4) | 104 | 88-116 |
| Urine (n=4) | 96 | 91-106 |
Linearity
To assess the linearity of the assay, five samples were spiked with high concentrations of IL-5 in various matrices and diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Background: IL-5
IL-5 (Interleukin-5) is a secreted cytokine that is expressed as a covalent dimer. It is produced by activated Th2 cells, eosinophils, mast cells, and iNKT cells and promotes eosinophilic and basophilic differentiation and activation. IL-5 signals through a receptor complex containing IL-5 R alpha and the Common beta Chain/CD131 on eosinophils and basophils. Naturally occurring soluble forms of IL-5 R alpha retain the ability to bind IL-5 and limit its bioavailability.
