Scientific Data Images for Human IFN-gamma Antibody (25718)

IFN‑? antibody in Human PBMCs by Immunocytochemistry (ICC).

IFN‑ gamma in Human PBMCs.

IFN-gamma was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) stimulated with PMA and ionomycin using 10 µg/mL Human IFN-gamma Monoclonal Antibody (Catalog # MAB285) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue).

Detection of IFN- gamma antibody in Human PBMCs antibody by Flow Cytometry.

Detection of IFN‑ gamma in Human PBMCs by Flow Cytometry.

Human peripheral blood mononuclear cells (PBMCs) treated with 50 ng/mL PMA, 1 ug/mL Ionomycin, and 3 uM Monensin overnight were stained with either (A) Mouse Anti-Human IFN- gamma Monoclonal Antibody (Catalog # MAB285) or (B) Mouse IgG2A Isotype Control (Catalog # MAB003) followed by anti-Mouse IgG PE-conjugated secondary antibody (Catalog # F0102B) and Mouse Anti-Human CD3 epsilon APC-conjugated Monoclonal Antibody (Catalog # FAB100A). To facilitate intracellular staining, cells were fixed and permeabilized with FlowX FoxP3 Fixation & Permeabilization Buffer Kit (Catalog # FC012).

IFN‑ gamma Inhibition of EMCV-induced Cytopathy and Neutralization by Human IFN‑ gamma Antibody.

IFN‑ gamma Inhibition of EMCV-induced Cytopathy and Neutralization by Human IFN‑ gamma Antibody.

Recombinant Human IFN-gamma (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-gamma (1 ng/mL) is neutralized (green line) by increasing concentrations of Human IFN-gamma Monoclonal Antibody (Catalog # MAB285). The ND50 is typically 0.02-0.06 µg/mL.

Applications for Human IFN-gamma Antibody (25718)

Recommended Usage

Immunocytochemistry

8-25 µg/mL
Sample: Immersion fixed human peripheral blood mononuclear cells (PBMCs) stimulated with PMA and ionomycin

Intracellular Staining by Flow Cytometry

0.25 µg/106 cells
Sample: Human PBMCs treated with PMA, Ionomycin, and Monensin fixed and permeabilized with FlowX FoxP3 Fixation & Permeabilization Buffer Kit (Catalog # FC012)

Neutralization

Measured by its ability to neutralize IFN‑ gamma inhibition of EMCV-induced cytopathy in the HeLa human cervical epithelial carcinoma cell line. Meager, A. (1987) in Lymphokines and Interferons, a Practical Approach. Clemens, M.J. et al. (eds): IRL Press. 129. The Neutralization Dose (ND50) is typically 0.02-0.06 µg/mL in the presence of 1 ng/mL Recombinant Human IFN‑ gamma.

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.
