Product overview
Human Interferon gamma SimpleStep ELISA® kit is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Interferon gamma protein in human serum, plasma, saliva and cell culture supernatant. Quantitate Human Interferon gamma with 3.428 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
-Single-wash protocol reduces assay time to 90 minutes or less
-High sensitivity, specificity and reproducibility from superior antibodies
-Fully validated in biological samples
-96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

Research areas

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
modificationsProteolytic processing produces C-terminal heterogeneity, with proteins ending alternatively at Gly-150, Met-157 or Gly-161. -

Example of human Interferon-gamma standard curve. Background-subtracted data values (mean +/- SD) are graphed.
-
Interpolated concentration of native Interferon-gamma was measured in duplicate at different sample concentrations. Undiluted samples are 2.5% stimulated PBMC cell culture supernatant. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). Sample dilutions are made in Sample Diluent NS.
-
Interpolated concentration of native Interferon-gamma was measured in duplicate in human PBMC cell culture supernatants. Sample dilutions are made in Sample Diluent NS. Human PBMCs were cultured for 46 hours in the presence or absence of 1.5% PHA-M. The concentrations of human Interferon gamma were measured in three different dilutions of the supernatant samples in duplicates and interpolated from the Interferon gamma standard curve. The interpolated values are plotted (mean +/- SD, n=2).
