Application Abreviews Notes
ELISA Use at an assay dependent concentration.

Use at an assay dependent dilution.

ELISpot Use at an assay dependent concentration.
Neutralising Use at an assay dependent concentration.

In vitro neutralization.  One Neutralizing Unit is defined as the total amount of antibodies sufficient for neutralizing one laboratory unit of recombinant Human IFNG (1 Unit = ~50 pg of pure Human IFNG).  Activity ≥ 10^4 Neutralizing U/mg protein.

ICC Use at an assay dependent concentration.

Follow an intracellular staining protocol.

WB Use at an assay dependent concentration. Predicted molecular weight: 19 kDa.

Use at an assay dependent dilution.

IHC-Fr Use at an assay dependent concentration.
Sandwich ELISA Use a concentration of 0.5 µg/ml. Can be paired for Sandwich ELISA with Mouse monoclonal [MD-1] to Interferon gamma (ab25014). For sandwich ELISA, use this antibody as Detection at 0.5µg/ml with Ab25014 as Capture.
IHC-P Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.

Target

  • FunctionProduced 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.
  • Tissue specificityReleased primarily from activated T lymphocytes.
  • Involvement in diseaseIn Caucasians, genetic variation in IFNG is associated with the risk of aplastic anemia (AA) [MIM:609135]. AA is a rare disease in which the reduction of the circulating blood cells results from damage to the stem cell pool in bone marrow. In most patients, the stem cell lesion is caused by an autoimmune attack. T-lymphocytes, activated by an endogenous or exogenous, and most often unknown antigenic stimulus, secrete cytokines, including IFN-gamma, which would in turn be able to suppress hematopoiesis.
  • Sequence similaritiesBelongs to the type II (or gamma) interferon family.
  • Post-translational
    modifications
    Proteolytic processing produces C-terminal heterogeneity, with proteins ending alternatively at Gly-150, Met-157 or Gly-161.
  • Cellular localizationSecreted.

  • Standard curve for Interferon gamma (Analyte: ab51240); dilution range 1pg/ml to 1µg/ml using Capture Antibody ab25014 at 5µg/ml and Detector Antibody ab25101 at 0.5µg/ml.
  • Ab25101 staining Human tonsil. Staining is localised to the cytoplasm and protein is secreted.
    Left panel: with primary antibody at 1 ug/ml. Right panel: isotype control.
    Sections were stained using an automated system DAKO Autostainer Plus , at room temperature. Sections were rehydrated and antigen retrieved with the Dako 3-in-1 antigen retrieval buffer EDTA pH 9.0 in a DAKO PT Link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 minutes. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 minutes and detected with Dako Envision Flex amplification kit for 30 minutes. Colorimetric detection was completed with diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that for manual staining we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required.
  • Anti-Interferon gamma antibody (ab25101) at 1 µg/ml + Recombinant Human Interferon gamma protein (ab51240) at 0.01 µg
