IFN‑ gamma Inhibition of EMCV-induced Cytopathy and Neutralization by Human IFN‑ gamma Antibody. Recombinant Human IFN-? (Catalog # 285-IF) reduces the Encephalomyocarditis Virus (EMCV)-induced cytopathy in the HeLa human cervical epithelial carcinoma cell line in a dose-dependent manner (orange line), as measured by crystal violet staining. Inhibition of EMCV activity elicited by Recombinant Human IFN-? (5 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human IFN-? Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-285-NA). The ND50is typically 0.1-0.3 µg/mL.

Background: IFN-gamma

Interferon-gamma (IFN-gamma, IFNG), also known as type II or Immune Interferon, exerts a wide range of immunoregulatory activities and is considered to be the prototype proinflammatory cytokine. Mature human IFN-gamma exists as a non-covalently linked homodimer of 20-25 kDa molecular weight variably glycosylated subunits. Glycosylation of IFN-gamma at sites Asn25 and Asn97 is critical for protease resistance. It shares 90% amino acid (aa) sequence identity with rhesus IFN-gamma, 59-64% with bovine, canine, equine, feline, and porcine IFN‑ gamma, and 37-43% with cotton rat, mouse, and rat IFN-gamma. IFN-gamma dimers bind to IFN-gamma RI (alpha subunits) which then interact with IFN-gamma RII (beta subunits) to form the functional receptor complex of two alpha and two beta subunits. Inclusion of IFN-gamma RII increases the binding affinity for ligand and the efficiency of signal transduction. IFN-gamma is produced by a variety of immune cells under inflammatory conditions, notably by T cells and NK cells. It plays a key function in host defense by promoting the development and activation of Th1 cells, chemoattraction and activation of monocytes and macrophages, up‑regulation of antigen presentation molecules, and immunoglobulin class switching in B cells. It also exhibits antiviral, antiproliferative, and apoptotic effects. In addition, IFN-gamma functions as an anti-inflammatory mediator by promoting the development of regulatory T cells and inhibiting Th17 cell differentiation. The pleiotropic effects of IFN-gamma contribute to the development of multiple aspects of atherosclerosis.

Human IFN-gamma Antibody
By Anonymous on 04/13/2018
Application: IHC Sample Tested: Adult brain Species: Human

Published in https://www.ncbi.nlm.nih.gov/pubmed/28169287
Used at 10ug/ml.
Briefly, frozen brain sections were fixed in 4% PFA (Fisher Scientific), followed by antigen retrieval using heating in acid citric buffer (Vector, Burlingame, CA, USA). Endogenous avidin-biotin was blocked for 15 min (Vector). Sections were incubated with 10% horse serum in PBS (Biosera, Boussens, France) and Fc Receptor Blocking Solution was added (Human TruStain FcX Biolegend,
London, UK). Primary antibody was added overnight at 4 °C and detected with donkey anti-goat-biotin (ab6578, Abcam), followed by streptavidin-alkaline phosphatase (SA-5100, Vector) and visualised with the Vector Blue Alkaline Phosphatase Substrate Kit III (Vector).
