概述
货号	MAB585-100
别名	IFG; IFI; IFNG; IFN-gamma; Immune interferon; interferon gamma; interferon, gamma
全称	Interferon gamma
反应种属	Rat
应用	Western Blot(1 µg/mL)
目标/特异性	Detects rat IFN-gamma in Western blots. In Western blots, this antibody shows less than 1% cross-reactivity with recombinant mouse (rm) IFN‑ gamma and no cross-reactivity with rhIFN‑ gamma.
使用方法	Western Blot: 1 µg/mL Neutralization: Measured by its ability to neutralize IFN‑ gamma inhibition of EMCV-induced cytopathy in the L‑929 mouse fibroblast cell line. Vogel, S. and M. Hogan (1995) in Current Protocols in Immunology. Ciocio, R. (ed); John Wiley & Sons, Inc. p. 6. 9. 1. The Neutralization Dose (ND₅₀) is typically 0.5-1.5 µg/mL in the presence of 2.5 ng/mL Recombinant Rat IFN‑ gamma.

背景	Interferon-gamma (IFN-gamma ), also known as type II or immune interferon, exerts a wide range of immunoregulatory activities and is considered to be the prototype proinflammatory cytokine (1, 2). Mature rat IFN-gamma exists as a noncovalently linked homodimer of 20-25 kDa variably glycosylated subunits (3). It shares 86% amino acid sequence identity with mouse IFN-gamma and 37-45% with bovine, canine, cotton rat, equine, feline, human, porcine, and rhesus 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 (4, 5). IFN-gamma is produced by a variety of immune cells under inflammatory conditions, notably by T cells and NK cells (6). It plays a key role in host defense by promoting the development and activation of Th1 cells, chemoattraction and activation of monocytes and macrophages, upregulation of antigen presentation molecules, and immunoglobulin class switching in B cells. It also exhibits antiviral, antiproliferative, and apoptotic effects (6, 7). In addition, IFN-gamma functions as an anti-inflammatory mediator by promoting the development of regulatory T cells and inhibiting Th17 cell differentiation (8, 9). The pleiotropic effects of IFN-gamma contribute to the development of multiple aspects of atherosclerosis (7).

IFN‑ gamma Inhibition of EMCV-induced Cytopathy and Neutralization by Rat IFN‑ gamma Antibody. Recombinant Rat IFN‑ gamma (Catalog # 585-IF) reduces the Encephalomyocarditis Virus (EMCV)-induced cytopathy in the L‑929 mouse fibroblast cell line in a dose-dependent manner (orange line). Inhibition of EMCV activity elicited by Recombinant Rat IFN‑ gamma (2.5 ng/mL) is neutralized (green line) by increasing concentrations of Rat IFN‑ gamma Monoclonal Antibody (Catalog # MAB585). The ND₅₀ is typically 0.5-1.5 µg/mL.
