Scientific Data Images for Human IFN-gamma R1/CD119 Antibody

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 Mono-clonal Antibody (Catalog # MAB6732). The ND₅₀ is typically 0.03-0.15 µg/mL.

Applications for Human IFN-gamma R1/CD119 Antibody

Application

Recommended Usage

Neutralization

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.

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.
