Product Summary for Human IL-23 Quantikine ELISA Kit

The Quantikine Human IL-23 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human IL-23 in cell culture supernates, serum, and plasma. It contains Sf 21-expressed recombinant human IL-23 and has been shown to accurately quantitate the recombinant factor. Results obtained for naturally occurring human IL-23 showed linear curves that were parallel to the standard curves obtained using the kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring human IL-23.

< 0.5% cross-reactivity observed with available related molecules. < 50% cross-species reactivity observed with species tested.

Interference

No significant interference observed with available related molecules.

Precision

Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.

Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision.

Recovery for Human IL-23 Quantikine ELISA Kit

The recovery of human IL-23 spiked to levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=4) 93 87-107
EDTA Plasma (n=4) 95 86-106
Heparin Plasma (n=4) 93 85-99
Serum (n=4) 98 88-105

Linearity

To assess the linearity of the assay, samples containing and/or spiked with high concentrations of IL-23 were serially diluted with the Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Background: IL-23

IL-23 (Interleukin-23) is a disulfide-linked cytokine composed of a p19 subunit that is unique to IL-23 and a p40 subunit that is shared with IL-12. It is produced by activated macrophages, microglia, and monocyte-derived dendritic cells in response to pathogens. IL-23 induces the earliest recruitment of neutrophils to the site of infection and promotes the development and maintenance of Th17 cells. It also enhances the development of Th17 mediated autoimmunity and tumor progression. IL-23 signals through a receptor complex consisting of IL-12 R beta 1 and IL-23 R. This complex is expressed in mouse Th1 and Th2 cells, bone marrow dendritic cells, activated macrophages and CD4+ CD45Rb(low) memory T cells.
