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 Mouse Anti-Human IFN-gamma (2 ng/mL) is neutralized (green line) by increasing concentrations of Human IFN-gamma R1/CD119 Monoclonal Antibody (Catalog # MAB6731). The ND50 is typically 0.01-0.03 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) residue 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 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.

By Anonymous on 07/16/2018
Application: WB Sample Tested: Cancer Cells Species: Human

Cancer cells as indicated were treated with or without INF-g (10ng/ml) for 24h. Total cell lysates were subjected to western blot. PVDF membrane were probed with 1mm/ml Human Human IFN-gamma R1/CD119 Antibody (MAB6731). A specific band was detected for IFN-gamma R1/CD119 at approximately 43kDa. This experiment was conducted under reducing conditions
