Target

  • Function

    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.
  • Tissue specificity

    Released primarily from activated T lymphocytes.
  • Involvement in disease

    In 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 similarities

    Belongs 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 localization

    Secreted.

Images

  • Immunohistochemical analysis of paraffin-embedded human tonsil tissue labeling Interferon gamma with ab231036 at 1/500 dilution, followed by a ready to use Goat Anti-Rabbit IgG H&L (HRP) (ab97051). Sporadic cytoplasmic staining in limphocytes of human tonsil is observed (PMID: 21838712). Counter stained with hematoxylin.

    Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is a ready to use Goat Anti-Rabbit IgG H&L (HRP) (ab97051).

    Perform heat mediated antigen retrieval using ab93684 (Tris/EDTA buffer, pH 9.0).

  • All lanes : Anti-Interferon gamma antibody [EPR21704] (ab231036) at 1/1000 dilution

    Lane 1 : Untreated NK-92 (human malignant non-Hodgkin's lymphoma natural killer cell), whole cell lysate.
    Lane 2 : NK-92 treated with 80µM ab120297 PMA (Phorbol-12-myristate-13-acetate) and 3 µM Ionomycin for 5 hours, then added 300 ng/ml BFA for 4 hours.

    Lysates/proteins at 20 µg per lane.

    Secondary
    All lanes : Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/20000 dilution

    Predicted band size: 19 kDa
    Observed band size: 20 kDa
    why is the actual band size different from the predicted?


    Exposure time: 8 seconds


    Blocking/dilution buffer and concentration: 5% NFDM/TBST

    Expression of IFN Gamma in NK-92 could be induced by PMA and Ionomycin treatment according to the literature (PMID: 23129404).

  • Immunohistochemical analysis of paraffin-embedded NK-92 cells labeling Interferon gamma with ab231036 at 1/500 dilution, followed by a ready to use Goat Anti-Rabbit IgG H&L (HRP) (ab97051). Nearly no staining on untreated NK92 cells (A) and positive staining on treated NK92 cells (B) (treated with 80 μM ab120297 PMA (Phorbol-12-myristate-13-acetate) and 3 μM Ionomycin for 5 hours, then with 300 ng/ml BFA for 4 hours) is observed (PMID:23129404). Counter stained with hematoxylin.

    Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is a ready to use Goat Anti-Rabbit IgG H&L (HRP) (ab97051).

    Perform heat mediated antigen retrieval using ab93684 (Tris/EDTA buffer, pH 9.0).

  • Flow cytometric analysis of 4% paraformaldehyde-fixed, 90% methanol permeabilized NK-92 (human malignant non-Hodgkin's lymphoma natural killer cell) cell line treated with 80 μM ab120297 PMA (Phorbol-12-myristate-13-acetate) and 3 μM Ionomycin for 5 hours, then 300 ng/ml BFA was added for 4 hours labeling Interferon gamma with ab231036 at 1/60 (red) and untreated control (green). Compared with a Rabbit monoclonal IgG-Isotype Control (ab172730) (black) and an unlabeled control (cells incubated with secondary anibody only) (blue). Goat anti rabbit IgG (Alexa Fluor® 488, ab150077), at 1/2000 dilution was used as the secondary antibody.
