Applications

Recommended Concentration
Sample
Neutralization
Measured by its ability to neutralize IFN-beta inhibition of EMCV-inducedcytopathy in the HeLa human cervicalepithelial 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 7-21μg/mL in the presence of50 pg/mL Recombinant Human IFN-beta.

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-beta Antibody.
Recombinant HumanIFN-beta (Catalog # 8499-IF)reduces theEncephalomyocarditis Virus(EMCV)-inducedcytopathy in theHeLa human cervical epithelialcarcinoma cell line in a dose-dependentmanner (orange line),as measured by crystal violetstaining. Inhibition of EMCVactivity elicited by RecombinantHuman IFN-beta (50 pg/mL) isneutralized (green line) byincreasing concentrations of Recombinant Human IFN-beta MonoclonalAntibody (Catalog # MAB814R).The ND50 is typically 7-21μg/mL.

Background: IFN-beta

Interferon beta (IFN-beta ) is synthesized and secreted by fibroblasts and many other cell types in response to pathogens. IFN-beta binding to type I interferon receptors induces the upregulation of IRF-7 and activation of Rnase L. IRF-7 can exert a positive feedback on IFN-beta production. RNase L cleaves both viral and cellular single stranded mRNA, thereby limiting viral replication and dissemination.
