Detects human IFN-gamma R2 in direct ELISAs and Western blots. In direct ELISAs and Western blots, less than 1% cross‑reactivity with recombinant human IFN‑ gamma R1 is observed.
Polyclonal Goat IgG
Mouse myeloma cell line NS0-derived recombinant human IFN-gamma R2 Ala22-Gln247 Accession # P38484
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.
Recombinant Human IFN-gamma R2
2.5 µg/106 cells
Measured by its ability to neutralize IFN‑ gamma R2-mediated inhibition of EMCV-induced cytopathy in the HeLa human cervical epithelial carcinoma cell line [Meager, A. (1987) in Lymphokines and Interferons, a Practical Approach. Clemens, M.J. et al. (eds): IRL Press. 129]. The Neutralization Dose (ND50) is typically 0.5-2.5 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 R2 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 Goat Anti-Human IFN‑ gamma R2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF773). The ND50 is typically 0.5-2.5 µg/mL.

Background: IFN-gamma R2
Interferon gamma Receptor 2 (IFN-gamma R2) is a type II transmembrane protein that associates with IFN-gamma R1 to form a high affinity receptor complex for IFN-gamma. IFN‑ gamma R2 is required for signal transduction but does not bind IFN-gamma by itself.
