SpecificityThis antibody reacts with both mouse and rat Interferon gamma. Clone DB-1 exhibits high affinity binding to the natural and recombinant forms and effectively neutralises the anti viral activity of IFN-gamma. It also blocks the induction of La antigen expression on murine keratinocytes.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Application notesBL: Use at an assay dependent dilution
ELISA: Use at a concentration of 10 µg/ml, 100ul/well as coating antibody
Neut: Use at an assay dependent dilution.
Not tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
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 modificationsProteolytic processing produces C-terminal heterogeneity, with proteins ending alternatively at Gly-150, Met-157 or Gly-161.
