Applications

Recommended Concentration

Sample

ELISA

This antibody functions as an ELISA capture antibody when paired with Goat Anti-Porcine IFN‑ gamma Antigen Affinity-purified Polyclonal Antibody (Catalog # AF985).

This product is intended for assay development on various assay platforms requiring antibody pairs. We recommend the Porcine IFN-gamma DuoSet ELISA Kit (Catalog # DY985) for convenient development of a sandwich ELISA.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Porcine IFN‑ gamma ELISA Standard Curve. Recombinant Porcine IFN-gamma protein was serially diluted 2-fold and captured by Mouse Anti-Porcine IFN-gamma Monoclonal Antibody (Catalog # MAB9852) coated on a Clear Polystyrene Microplate (Catalog # DY990). Goat Anti-Porcine IFN-gamma Antigen Affinity-purified Polyclonal Antibody (Catalog # AF985) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998) followed by Substrate Solution (Catalog # DY999) and stopping the enzymatic reaction with Stop Solution (Catalog # DY994).

Background: IFN-gamma

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 porcine IFN-gamma exists as a noncovalently linked homodimer of 20‑25 kDa variably glycosylated subunits (3). It shares 72%‑79% amino acid sequence identity with bovine, canine, equine, and feline IFN-gamma and 41%‑57% with cotton rat, human, mouse, rat, 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, anti-proliferative, 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).
