Product Summary for Human IL-6 Quantikine ELISA Kit
The Quantikine Human IL-6 Immunoassay is a 4.5 hour solid phase immunoassay designed to measure human IL-6 in cell culture supernates, serum, plasma, and urine. It contains recombinant human IL-6 and antibodies raised against the recombinant protein. Natural human IL-6 showed dose-response curves that were parallel to the standard curves obtained using the Quantikine kit standards, indicating that this kit can be used to determine relative levels of natural human IL-6.

Reactivity
Human
Specificity
Natural and recombinant human IL-6.
Cross-reactivity
Cross-reactivity observed with 1 or more available related molecules. 50% cross-species reactivity observed with species tested.
Interference
Interference observed with 1 or more available related molecules.
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 IL-6 Quantikine ELISA Kit
The recovery of human IL-6 spiked to three different levels in samples throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 102 | 82-122 |
| EDTA Plasma (n=4) | 97 | 90-102 |
| Heparin Plasma (n=4) | 96 | 90-99 |
| Serum (n=4) | 96 | 89-103 |
| Urine (n=4) | 97 | 89-101 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of human IL-6 in various matrices were diluted with the calibrator diluent to produce samples with values within the dynamic range of the assay.

Background: IL-6
IL-6 (Interleukin-6) is a pleiotropic cytokine that acts in the acute phase reaction, inflammation, hematopoiesis, bone metabolism, and cancer progression. It contributes to chronic inflammation in obesity, inflammatory bowel disease, arthritis, sepsis, and atherosclerosis. IL-6 signals through a receptor complex of IL-6 R alpha and gp130. gp130 is also a component of the receptors for CLC, CNTF, CT-1, IL-11, IL-27, LIF, and OSM. Soluble forms of IL-6 R alpha are generated by both alternative splicing and proteolytic cleavage. In a mechanism known as trans-signaling, complexes of soluble IL-6 and IL-6 R alpha elicit responses from gp130-expressing cells that lack cell surface IL-6 R alpha.
