Simple Western™ 1:10 - 1:50

Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/mL BSA, 50% glycerol, and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

Specificity/Sensitivity

IFNAR2 (E7R3A) Rabbit Monoclonal Antibody recognizes endogenous levels of total IFNAR2 protein. This clone recognizes isoforms 1, 2, and 3 of mouse IFNAR2 protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of mouse IFNAR2 protein.

Background

Interferon alpha/beta receptor 2 (IFNAR2) is one of the two protein subunits that comprise the type I interferon (IFN-I) surface receptor. IFNAR2 is a class II helical cytokine receptor with an ectodomain composed of two fibronectin type III-like subdomains, D1 and D2, and an unstructured intracellular domain (ICD) (1,2). IFNAR2 is expressed on most nucleated cells (3). IFN-Is bind the IFN receptor, leading to the dimerization of IFNAR2 and IFNAR1 subunits, and the activation of Janus family kinase (JAK) and signal transducer and activator of transcription (STAT) signaling pathways (4,5). JAK1 is associated with IFNAR2, and STAT1 and STAT2 are constitutively bound to the intracellular domain (ICD) of IFNAR2 (6,7). The formation of the transcription factor IFN-stimulated gene factor 3 (ISGF3), which is a complex made up of the pSTAT1-pSTAT2 heterodimer and interferon regulatory factor 9 (IRF-9), leads to the transcription of interferon-stimulated genes (ISGs) (8). IFN-I subtypes have differential binding affinity toward IFNAR2, contributing to differences in response potency (9). In contrast, IFN-αs all bind IFNAR1 with a low affinity and only IFN-β binds IFNAR1 with a relatively higher affinity (10). IFN-I signaling mediates various cellular responses, including antiviral responses, immunomodulatory responses, and antiproliferative effects (3). In the tumor microenvironment (TME), the presence of IFN-I signaling is associated with “hot” tumors in which key effector immune cells are present and is predictive of therapeutic response, whereas suppressed IFN-I signaling in the TME is associated with tumor progression and poorer outcomes (11,12). IFN-I signaling is being investigated as a therapeutic target for cancer, autoimmunity, sepsis, and viral infection (13,14).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.

Simple Western™ analysis of lysates (1 mg/mL) from J774A.1 cells treated with PNGase using IFNAR2 (E7R3A) Rabbit mAb #80537. The virtual lane view (left) shows the target band (as indicated) at 1:10 and 1:50 dilutions of primary antibody. The corresponding electropherogram view (right) plots chemiluminescence by molecular weight along the capillary at 1:10 (blue line) and 1:50 (green line) dilutions of primary antibody. This experiment was performed under reducing conditions on the Jess™ Simple Western instrument from ProteinSimple, a BioTechne brand, using the 12-230 kDa separation module.
