About This Kit
The Human Interferon gamma (Hu IFN-gamma) ELISA kit enables the quantification of Hu IFN-gamma in various biological samples, including human serum, plasma, buffered solutions, and cell culture medium. This assay is specifically designed to exclusively detect both natural and recombinant forms of Hu IFN-gamma.
Principle of the method
The Human IFN-gamma solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) follows a unique approach to measure the amount of the target molecule. It utilizes a matched pair of antibodies to capture the target and form a sandwich complex. The first antibody is pre-coated on the microplate wells, where samples, standards, or controls are added and bind to the immobilized antibody. The second antibody, acting as the detector, is then introduced, followed by the addition of a substrate solution that generates a measurable signal upon interaction with the enzyme-antibody-target complex. The intensity of this signal directly correlates to the concentration of the target present in the original specimen.
Target information
IFN gamma (Interferon gamma, Type II interferon) is a macrophage activation factor, and immune interferon that is produced primarily by T-lymphocytes and natural killer cells in response to antigens, mitogens, Staphylococcus enterotoxin B, phytohemaglutanin and other cytokines. IFN gamma is a dimeric protein consisting of two 146 amino acid subunits. IFN gamma is a glycoprotein that exists, functionally, as a homodimer of approximately 45 kDa. On SDS-PAGE, IFN gamma appears as a combination of 25, 20 and minor 15.5 kDa bands as a result of differential glycosylation. The biological activity of the IFN gamma homodimer is highly species specific. Human IFN gamma does not show cross-reactivity with mouse. IFN gamma function includes the following: antiviral activity, tumor antiproliferative activity, induction of class I and II MHC, macrophage activation, and enhanced immunoglobulin secretion by B lymphocytes. IFN gamma is involved in cytokine regulation and also acts synergistically with other cytokines. Activation of IFN gamma takes place through binding of IFN gamma receptor I and II, and activating the JAK-STAT pathway. IFN gamma does not show any homology with IFN alpha or IFN beta but human IFN gamma shows about 40% sequence homology with mouse IFN gamma. IFN gamma is upregulated by IL2, FGF basic, EGF and downregulated by vitamin D3 or DMN. IFN gamma gene mutations are associated with aplastic anemia.
