Description
Human IL-17F ELISpot Kit
Assay Genie ELISpot is a highly specific immunoassay for the analysis of IL-17F production and secretion from T-cells at a single cell level in conditions closely comparable to the in-vivo environment with minimal cell manipulation. This technique is designed to determine the frequency of IL-17F producing cells under a given stimulation and the comparison of such frequency against a specific treatment or pathological state. Utilising sandwich immuno-enzyme technology, Assay Genie ELISpot assays can detect both secreted IL-17F (qualitative analysis) and single cells that produce IL-17F (quantitative analysis). Cell secreted IL-17F is captured by coated antibodies avoiding diffusion in supernatant, protease degradation or binding on soluble membrane receptors. After cell removal, the captured IL-17F is revealed by tracer antibodies and appropriate conjugates.

The Human IL-17F ELISPOT Kit is a cutting-edge assay designed for the precise detection of IL-17F levels in human immune responses. This kit offers exceptional sensitivity and specificity, delivering consistent and conclusive results for a variety of research applications.IL-17F is a key cytokine involved in regulating inflammatory responses and immune cell activation. It plays a critical role in various autoimmune diseases, allergies, and infections, making it a valuable biomarker for studying these conditions and developing targeted treatments.
With its advanced technology and reliable performance, the Human IL-17F ELISPOT Kit is an essential tool for scientists and researchers looking to explore the complex mechanisms of immune regulation and inflammation in human health and disease.

A capture antibody highly specific for IL-17F is coated to the wells of a PVDF bottomed 96 well microtitre plate either during kit manufacture or in the laboratory. The plate is then blocked to minimise any non-antibody dependent unspecific binding and washed. Cell suspension and stimulant are added and the plate incubated allowing the specific antibodies to bind any IL-17F produced. Cells are then removed by washing prior to the addition of Biotinylated detection antibodies which bind to the previously captured IL-17F. Enzyme conjugated streptavidin is then added binding to the detection antibodies. Following incubation and washing, substrate is then applied to the wells resulting in coloured spots which can be quantified using appropriate analysis software or manually using a microscope.
| Step | Procedure |
| 1. | For PVDF membrane activation, add 25 µl of 35% ethanol to every well. |
| 2. | Incubate plate at room temperature (RT) for 30 seconds. |
| 3. | Empty the wells by flicking the plate over a sink & gently tapping on absorbent paper. Thoroughly wash the plate 3x with 100 µl of PBS 1X per well. |
| 4. | Add 100 µl of diluted capture antibody to every well. |
| 5. | Cover the plate and incubate at 4°C overnight. |
| 6. | Empty the wells as previous and wash the plate once with 100 µl of PBS 1X per well. |
| 7. | Add 100 µl of blocking buffer to every well. |
| 8. | Cover the plate and incubate at RT for 2 hours. |
| 9. | Empty the wells as previous and thoroughly wash once with 100 µl of PBS 1X per well. |
| 10. | Add 100 µl of sample, positive and negative controls cell suspension to appropriate wells providing the required concentration of cells and stimulant. |
| 11. | Cover the plate and incubate at 37°C in a CO2 incubator for an appropriate length of time (15-20 hours). Note: do not agitate or move the plate during this incubation. |
| 12. | Empty the wells and remove excess solution then add 100 µl of Wash Buffer to every well. |
| 13. | Incubate the plate at 4°C for 10 min. |
| 14. | Empty the wells as previous and wash the plate 3x with 100 µl of Wash Buffer. |
| 15. | Add 100 µl of diluted detection antibody to every well. |
| 16. | Cover the plate and incubate at RT for 1 hour 30 min. |
| 17. | Empty the wells as previous and wash the plate 3x with 100 µl of Wash Buffer. |
| 18. | Add 100 µl of diluted Streptavidin-conjugate to every well. |
| 19. | Cover the plate and incubate at RT following the supplier's instructions. |
| 20. | Empty the wells and wash the plate 3x with 100 µl of Wash Buffer. |
| 21. | Peel of the plate bottom and wash both sides of the membrane 3x under running distilled water, once washing complete remove any excess solution by repeated tapping on absorbent paper. |
| 22. | Add 100 µl of ready-to-use substrate buffer to every well. |
| 23. | Following the supplier's instructions, incubate the plate for 5-15 min monitoring spot formation visually throughout the incubation period to assess sufficient colour development. |
| 24. | Empty the wells and rinse both sides of the membrane 3x under running distilled water. Completely remove any excess solution by gentle repeated tapping on absorbent paper Read Spots: allow the wells to dry and then read results. The frequency of the resulting coloured spots. |
| UniProt Protein Function: | Ligand for IL17RA and IL17RC (PubMed:17911633). The heterodimer formed by IL17A and IL17F is a ligand for the heterodimeric complex formed by IL17RA and IL17RC (PubMed:18684971). Involved in stimulating the production of other cytokines such as IL6, IL8 and CSF2, and in regulation of cartilage matrix turnover (PubMed:11591732, PubMed:11591768, PubMed:11574464). Also involved in stimulating the proliferation of peripheral blood mononuclear cells and T-cells and in inhibition of angiogenesis (PubMed:11591732). Plays a role in the induction of neutrophilia in the lungs and in the exacerbation of antigen-induced pulmonary allergic inflammation. |
| NCBI Summary: | The protein encoded by this gene is a cytokine that shares sequence similarity with IL17. This cytokine is expressed by activated T cells, and has been shown to stimulate the production of several other cytokines, including IL6, IL8, and CSF2/GM_CSF. This cytokine is also found to inhibit the angiogenesis of endothelial cells and induce endothelial cells to produce IL2, TGFB1/TGFB, and monocyte chemoattractant protein-1.
