Human IL-23 High Sensitivity Magnetic Luminex® Performance Assay Summary

Panel	Luminex Performance Human High Sensitivity Cytokine Panel B
Assay Type	Magnetic bead-based multiplex assay for the Luminex^® platform
Format	1 x 96-well microplate and Magnetic antibody-coated beads
Species	Human
Analytes Detected	Please see analyte list in assay customization tool below.
Performance Validation	Our Luminex High Performance Assays undergo our most extensive validation testing. All Luminex High Performance Assay Panels are validated for use with serum and plasma samples. Some High Performance Assays are additionally validated for cell culture supernatants, milk, saliva, or urine, as indicated on the individual product data sheets. Luminex High Performance Assays are tested for sensitivity (three-quarters the low standard), intra-assay precision, inter-assay precision, and to ensure assay linearity for validated sample types. Recovery values for individual samples in validated sample types are also tested. Validation data for each analyte can be found in the product datasheet.

Precision

	Intra-Assay Precision			Inter-Assay 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 forty-three separate assays to assess precision between assays.

More Information About Magnetic Bead-based Multiplex Kits For The Luminex^® Platform

Magnetic Luminex High Performance Assays are designed for use with the Luminex MAGPIX CCD Imager. Alternatively, kits can be used with the Luminex 100/200™ or FLEXMAP 3D, dual laser, flow-based sorting and detection platforms.

Analyte-specific antibodies are pre-coated onto color-coded microparticles. Microparticles, standards, and samples are pipetted into wells and the immobilized antibodies bind the analytes of interest. After washing away any unbound substances, a biotinylated antibody cocktail specific to the analytes of interest is added to each well. Following a wash to remove any unbound biotinylated antibody, Streptavidin-Phycoerythrin conjugate (Streptavidin-PE), which binds to the biotinylated detection antibodies, is added to each well. A final wash removes unbound Streptavidin-PE and the microparticles are resuspended in buffer and read using the Luminex or Bio-Plex analyzer. One laser is bead-specific and determines which analyte is being detected. A magnet in the analyzer captures and holds the superparaMagnetic microparticles in a monolayer. Two spectrally distinct Light Emitting Diodes (LEDs) illuminate the beads. One LED identifies the analyte that is being detected and the second LED determines the magnitude of the PE-derived signal, which is in direct proportion to the amount of analyte bound. Each well is imaged with a CCD camera. Kits can also be used with Luminex 100/200 or a Bio-Rad Bio-Plex dual laser, flow-based systems.

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.
