  • 产品概述

    Abcam’s IFN gamma Human High Sensitivity in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of IFN gamma in Human sera, plasmas, buffered solutions and cell culture media.

    A monoclonal antibody specific for IFN gamma has been coated onto the wells of the microtiter strips provided. Samples, including standards of known IFN gamma concentrations, control specimens or unknowns are pipetted into these wells. During the first incubation, the standards or samples and a biotinylated monoclonal antibody specific for IFN gamma are simultaneously incubated. After washing, the enzyme Streptavidin-HRP, that binds the biotinylated antibody is added, incubated and washed. A TMB substrate solution is added which acts on the bound enzyme to induce a colored reaction product. The intensity of this colored product is directly proportional to the concentration of IFN gamma present in the samples. 

    This kit will recognize both endogenous and recombinant Human IFN gamma.

性能

  • 相关性Mammalian Interferon gamma is mainly produced by T lymphocytes and NK cells. It is a pleiotropic cytokine involved in the regulation of nearly all phases of immune and inflammatory responses,including the activation, growth and differentiation of T cell, B cells, macrophages, NK cells and other cell types such as endothelial cells and fibroblasts. It has weak antiviral and antiproliferative activity, and poteniates the antiviral and anti tumor effects of IFN alpha / beta (type I interferon). It is upregulated by IL2, FGF basic, EGF and downregulated by vitamin D3 or DMN. Labile at pH 2.

Human IFN gamma High Sensitivity ELISA Kit 图像

  • IFN gamma measured in cell culture supernatants from control or treated (48 hours; 2% PHA-M; LifeTechnologies) PBMCs, diluted 1/100-1/10000 (duplicates +/- SD).

  • IFN gamma measured in undiluted cell culture supernatants from control or stimulated (48 hours with 50 ng x mL-1 PMA (ab120297) and 1 μM ionomycin (ab120116)) Jurkat cells. Control sample was below limit of detection (<0.57 pg x mL-1)  (duplicates +/- SD).

  • IFN gamma measured in undiluted human biological fluids; mouse and rat samples (plasma and serum) were below limit of detection (duplicates +/- SD).

  • Dilution curves of IFN gamma (ab46048) and NIBSC standard (87/586). One ng of standard IFN gamma corresponds to 12.3 (+/- 1.3) IU NIBSC 87/586. Background signal subtracted (duplicates; +/- SD).
