Detects human IFN‑ gamma R1/CD119 in direct ELISAs and Western blots. In direct ELISAs, no cross-reactivity with recombinant mouse IFN-gamma R1, recombinant human (rh) IFN-gamma R2, or rhIL-10 R beta is observed.
Monoclonal Mouse IgG1 Clone # GIR208
Protein A or G purified from hybridoma culture supernatant
Human placenta-derived IFN‑ gamma R1/CD119
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
<0.10 EU per 1 μg of the antibody by the LAL method.
Measured by its ability to neutralize IFN‑ gamma R1/CD119-mediated inhibition of EMCV-induced cytopathy in the HeLa human cervical epithelial carcinoma cell line. The Neutralization Dose (ND50) is typically 0.03-0.15 µg/mL in the presence of 2 ng/mL Recombinant Human 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 Human IFN‑ gamma R1/CD119 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). Inhibition of EMCV activity elicited by Recombinant Human IFN‑ gamma (2 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human IFN‑ gamma R1/CD119 Monoclonal Antibody (Catalog # MAB6732). The ND50 is typically 0.03‑0.15 µg/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% amino acid 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% aa identity 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.
