Detects mouse IFN-gamma R1/CD119 in ELISAs. In sandwich immunoassays, no cross-reactivity or interference with recombinant mouse (rm) IFN‑ alpha / beta R1, rmIFN-gamma R2, recombinant human (rh) IFN-gamma R1, rhIL-20 R alpha, rhIL-20 R beta, rmIL-20 R alpha, rhIL-22BP or rmIL-22BP is observed.
Monoclonal Rat IgG2B Clone # 170911
Protein A or G purified from hybridoma culture supernatant
Measured by its ability to neutralize IFN‑ gamma R1/CD119-mediated inhibition of EMCV-induced cytopathy in the L‑929 mouse fibroblast cell line. Vogel, S. N. et al. (1982) Infect. Immun. 38:681. The Neutralization Dose (ND50) is typically 4-20 ng/mL in the presence of 1 ng/mL Recombinant Mouse IFN‑ gamma.
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.
IFN‑ gamma Inhibition of EMCV-induced Cytopathy and Neutralization by Mouse IFN‑ gamma R1/CD119 Antibody. Recombinant Mouse IFN‑ gamma (Catalog # 485-MI) reduces the Encephalomyocarditis Virus (EMCV)-induced cytopathy in the L‑929 mouse fibroblast cell line in a dose-dependent manner (orange line), as measured by Resazurin. Inhibition of EMCV activity elicited by Recombinant Mouse IFN‑ gamma (1 ng/mL) is neutralized (green line) by increasing concentrations of Mouse IFN‑ gamma R1/CD119 Monoclonal Antibody (Catalog # MAB10262). The ND50 is typically 4-20 ng/mL.

Background: IFN-gamma R1/CD119
The high-affinity IFN-gamma receptor complex is made up of two type I membrane proteins, IFN-gamma R1 (IFN-gamma R alpha ) and IFN-gamma R2 (IFN-gamma R beta ). Both proteins are members of the type II cytokine receptor family and share approximately 52% overall sequence identity. IFN-gamma R1 is the ligand-binding subunit that is necessary and sufficient for IFN-gamma binding and receptor internalization. IFN-gamma R2 is required for IFN-gamma signaling but does not bind IFN-gamma by itself. Human IFN-gamma R1 cDNA encodes a 499 amino acid (aa) protein with a 17 aa signal peptide, a 228 aa extracellular domain, a 23 aa transmembrane domain, and a 221 aa intracellular domain. Human and mouse IFN-gamma R1 share 52% amino acid sequence similarity and bind IFN-gamma in a species-specific manner. IFN-gamma R1 is constitutively expressed in most cell types. Soluble IFN-gamma R1 that binds IFN-gamma has been detected in biological fluids.
