Description
Murine IFN-gamma ELISpot Kit
Assay Genie ELISpot is a highly specific immunoassay for the analysis of IFN-γ 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 IFN-γ 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 IFN-γ (qualitative analysis) and single cells that produce IFN-γ (quantitative analysis). Cell secreted IFN-γ is captured by coated antibodies avoiding diffusion in supernatant, protease degradation or binding on soluble membrane receptors. After cell removal, the captured IFN-γ is revealed by tracer antibodies and appropriate conjugates.
Murine IFN-gamma ELISpot Kit
The Murine IFN-gamma ELISPOT Kit is a powerful tool for the detection and quantification of interferon-gamma (IFN-gamma) secreting cells in murine samples. This kit is specifically designed for use with murine samples and provides high sensitivity and accuracy, allowing for reliable and reproducible results.IFN-gamma is a key player in the immune response, playing a critical role in the activation of macrophages, natural killer cells, and T cells. By measuring IFN-gamma production at the single-cell level, researchers can gain valuable insights into immune responses, vaccine efficacy, and autoimmune diseases in murine models.
With its easy-to-follow protocol and quick assay time, the Murine IFN-gamma ELISPOT Kit is an essential tool for researchers studying murine immunology and inflammation. Whether investigating infectious diseases, cancer immunotherapy, or autoimmune disorders, this kit provides the precision and sensitivity needed for accurate data analysis and interpretation.

A capture antibody highly specific for IFN-γ 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 IFN-γ produced. Cells are then removed by washing prior to the addition of Biotinylated detection antibodies which bind to the previously captured IFN-γ. 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: | IFNG: Produced by lymphocytes activated by specific antigens or mitogens. IFN-gamma, in addition to having antiviral activity, has important immunoregulatory functions. It is a potent activator of macrophages, it has antiproliferative effects on transformed cells and it can potentiate the antiviral and antitumor effects of the type I interferons. Homodimer. Released primarily from activated T lymphocytes. Belongs to the type II (or gamma) interferon family. |

| NCBI Summary: | This gene encodes a soluble cytokine that is a member of the type II interferon class. The encoded protein is secreted by cells of both the innate and adaptive immune systems. The active protein is a homodimer that binds to the interferon gamma receptor which triggers a cellular response to viral and microbial infections. Mice deficient in this gene have increased susceptibility to viral, bacterial and parasitic infections and to several autoimmune diseases. [provided by RefSeq, Dec 2015] |
