Our Abpromise guarantee covers the use of ab9805 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
Sandwich ELISA Use at an assay dependent dilution. Can be paired for Sandwich ELISA with Mouse monoclonal [GIF-3] to Interferon gamma (ab9801). PubMed: 9458493Use as capture antibody with recommended pair. sELISA can be used to determine IFN-g concentration in the cultures of human peripheral blood mononuclear cells.
Indirect ELISA Use at an assay dependent dilution.
WB Use at an assay dependent dilution.


  • 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

    Proteolytic processing produces C-terminal heterogeneity, with proteins ending alternatively at Gly-150, Met-157 or Gly-161.
  • Cellular localization

Customer reviews and Q&As


Yes, antibodies of clones GIF3 and GIF-10 have been used in a sandwich ELISA. The sensitivity of the assay is 300 pg/ml. For the sandwich ELISA, antibody GIF-3 was labelled with biotin. Specific reference for this is Osna N et al. Chronic hepatitis C: T-helper1/T-helper2 imbalance could cause virus persistence in peripheral blood. Scand J Clin Lab Invest 57:703-10 (1997). sELISA.
