IFN gamma elispot set

Human IFN gamma ELISpot Set

Cat. Num. AAA335738

• Gene Names: IFNG; IFG; IFI
• Reactivity: Human. No cross reactivity with other human cytokines. Cross reactivity with simian IFN-g.
• Synonyms: IFN gamma; Human IFN gamma ELISpot Set; IFN-g (with non-sterile-plate); IFN gamma elispot set

• Reactivity: Human. No cross reactivity with other human cytokines. Cross reactivity with simian IFN-g.
• Specificity: The assay recognizes natural human IFNgamma. To define the specificity several proteins were tested for cross reactivity. There was no cross reactivity observed for any protein tested (IL-1alpha, IL-1beta, IL-10, IL-12, IL-4, IL-6, TNFalpha, IL-8, and IL-13). This testing was performed using the equivalent human IFNgamma antibody pair in an ELISA assay.
• Sequence Length: 166

• Intended Uses: ELISpot is a highly specific immunoassay for the analysis of cytokine and other soluble molecule 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 cytokine producing cells under a given stimulation and the comparison of such frequency against a specific treatment or pathological state. The ELISpot assay constitutes an ideal tool in the investigation of Th1 / Th2 responses, vaccine development, viral infection monitoring and treatment, cancerology, infectious disease, autoimmune diseases and tranplantation. Utilising sandwich immuno-enzyme technology, ELISpot assays can detect both secreted cytokines and single cells that simultaneously produce multiple cytokines. Cell secreted cytokines or soluble molecules are captured by coated antibodies avoiding diffusion in supernatant, protease degradation or binding on soluble membrane receptors. After cell removal, the captured cytokines are revealed by tracer antibodies and appropriate conjugates.

Principle of the assay: A capture antibody highly specific for the analyte of interest 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 analytes produced. Cells are then removed by washing prior to the addition of Biotinylated detection antibodies which bind to the previously captured analyte. 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.

NCBI Description

This gene encodes a member of the type II interferon family. The protein encoded is a soluble cytokine with antiviral, immunoregulatory and anti-tumor properties and is a potent activator of macrophages. Mutations in this gene are associated with aplastic anemia.[provided by RefSeq, Nov 2009]

Uniprot Description

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.
