T helper type 17 (Th17) cells are involved in the immune response mounted against specific fungi and extracellular bacteria. In mice, Th17 cells develop from naive CD4+ T cells in the presence of TGF-beta and IL-6. These cytokines induce the STAT3-dependent expression of IL-21, IL-23 R, and the transcription factor, ROR gamma t. IL-21 and IL-23 regulate the establishment and clonal expansion of Th17 cells, while ROR gamma t-induced gene expression leads to the secretion of IL-17A, IL-17F, and IL-22. Cytokines secreted by Th17 cells stimulate chemokine secretion by resident cells, leading to the recruitment of neutrophils and macrophages to sites of inflammation. These cells, in turn, produce additional cytokines and proteases that further exacerbate the immune response. In contrast to mouse Th17 differentiation, Th17 polarization in humans requires IL-1 beta, IL-6, IL-21, and IL-23, but seems to be less dependent upon TGF-beta. One other notable difference is that human Th17 cells secrete IL-26, an IL-10 family cytokine without a murine homologue. Cytokines produced by Th17 cells can have both beneficial and pathogenic effects. While they play a central role in eliminating harmful microbes, persistent secretion of Th17 cytokines promotes chronic inflammation and may be involved in the pathogenesis of inflammatory and autoimmune diseases, including rheumatoid arthritis, multiple sclerosis, and inflammatory bowel disorders.

- Magnetic format allows for easier wash steps
- Undergoes similar validation testing as Quantikine® ELISA Kits
- Precise and Specific
- Requires a small sample volume (<50 µL)
- Run your assay in just 3-5 hours
- Mass-calibrated standards for consistent results with every new lot of material
- Enough reagents for one 96-well plate
- Quick turn-around time: Kits are typically shipped within 1-2 days of ordering*
*Please allow additional time for international orders.
Performance Validation
R&D Systems 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.

Additional Information About Luminex Assays
All R&D Systems Luminex Assays are designed for use with any Luminex instrument including MAGPIX, Luminex 200, FLEXMAP 3D, and the INTELLIFLEX.
Luminex assays use color-coded, magnetic microparticles coated with analyte-specific antibodies to enable multiplex quantitation. During the assay, standards and samples are added to the wells, where target analytes bind to the capture antibodies. A biotinylated detection antibody cocktail is then introduced, followed by a Streptavidin-PE conjugate that generates a fluorescent signal proportional to the amount of analyte present.
Each microparticle is identified by a unique signature and the signal intensity is measured using a Luminex instrument. These assays are designed to deliver reliable and reproducible results with validated antibody pairs and optimized protocols. They are well suited for applications that require sensitivity, accuracy, and confidence in your data while enabling efficient multiplexing to measure multiple targets simultaneously.
