mouse monoclonal IgG1; IFN-γ/Interferon gamma Antibody (G-23) is an IgG1 κ mouse monoclonal IFN-γ antibody that detects precursor and mature IFN-γ of human origin by WB, IP, IF, FCM and ELISA. IFN-γ/Interferon gamma Antibody (G-23) is available as the non-conjugated anti-IFN-γ antibody form, as well as multiple conjugated forms of anti-IFN-γ antibody, including agarose, HRP, PE, FITC and multiple Alexa Fluor® conjugates. Interferon (IFN)-γ is an antiviral and antiparasitic agent produced by CD4+/CD8+ lymphocytes and natural killer cells that undergo activation by antigens, mitogens or alloantigens. IFN-γ production modulates T cell growth and differentiation and inhibits the growth of B cells. Synthesis of IFN-γ is inducible by IL-2, FGF and EGF. The active form of IFN-γ is a homodimer with each subunit containing six helices. The dimeric structure of human IFN-γ is stabilized by non-covalent interactions through the interface of the helices. IFN-γ translated precursor is 166 amino acids, including the 23 amino acid secretory sequence. Multiple forms exist due to variable glycosylation and under non-denaturing conditions due to dimers and tetramers.
