Scientific Data Images for Human IFN‑ beta Antibody

Neutralization of IFN beta Anti-Viral Activity by Human IFN beta Antibody

Recombinant Human IFN beta ( 8499-IF) exhibits anti-viral activity in HeLa human cervical epithelial carcinoma cells infected with encephalomyocarditis (EMC). Inhibition of anti-viral activity elicited by Recombinant Human IFN beta (50 pg/mL) is neutralized by Human IFN beta Antibody (Catalog # MAB11127). The ND₅₀ for this effect is typically 2.00-20.0 µg/mL.

Applications for Human IFN‑ beta Antibody

Application

Recommended Usage

Neutralization

Measured by its ability to neutralize IFN‑ beta 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 2-20 µg/mL in the presence of 50 pg/mL Recombinant Human IFN‑ beta.

Formulation, Preparation, and Storage

Purification

Protein A or G purified from hybridoma culture supernatant

Reconstitution

Reconstitute at 0.5 mg/mL in sterile PBS. For liquid material, refer to CoA for concentration.

Formulation

Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.

Shipping

Background: IFN-beta

IFN-beta (interferon beta; also fibroblast IFN) is a secreted, monomeric 23-24 kDa member of the alpha/beta interferon family of molecules. It can be produced by almost all cell types in response to bacterial DNA or viral double-stranded RNA and is abundantly secreted by circulating plasmacytoid DCs. IFN-beta drives monocytic transformation into DCs, and it appears to stimulate a B cell switch from from IgM to IgG secretion. Mature human IFN-beta is 166 amino acids (aa) in length (aa 22-187) and contains one phosphorylation site at Ser140. There is one potential alternative start site at Met22. Full-length human IFN-beta (aa 22-187) shares 47% aa identity with mouse IFN-beta.
