Detects mouse IFN‑ alpha / beta R2 in direct ELISAs and Western blots. In Western blots, approximately 10% cross-reactivity with recombinant mouse (rm) IFN-gamma R2 and rmIL-20 R alpha is observed, 5% cross-reactivity with recombinant human (rh) IL-10 R beta, rmIFN-gamma RI, and rhIL-20 R beta is observed and less than 1% cross-reactivity with rhIFN-beta R alpha is observed.
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 Mouse IFN-alpha / beta R2
Measured by its ability to neutralize IFN‑ alpha / beta R2-mediated inhibition of EMCV-induced cytopathy in the L‑929 mouse fibroblast cell line. The Neutralization Dose (ND50) is typically 2-10 µg/mL in the presence of 30 pg/mL Recombinant Mouse Limitin.
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.
Limitin Inhibition of EMCV-induced Cytopathy and Neutralization by Mouse IFN‑ alpha / beta R2 Antibody. Recombinant Mouse Limitin (Catalog # 1535-LM) reduces the Encephalomyocarditis Virus (EMCV)-induced cytopathy in the L‑929 mouse fibroblast cell line in a dose-dependent manner (orange line). Inhibition of EMCV activity elicited by Recombinant Mouse Limitin (30 pg/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Mouse IFN‑ alpha / beta R2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1083). The ND50 is typically 2-10 µg/mL.

Background: IFN-alpha/beta R2
IFN-alpha / beta R2 belongs to the type II cytokine receptor family. It
complexes with IFN-alpha / beta R1 to form the signaling receptor complex for
the family of alpha and beta IFN subtypes. By alternative splicing, IFN-alpha / beta R2
can exist as a secreted soluble protein or as a type I membrane protein.
