Scientific Data Images for Human IFN-beta Antibody

IFN‑ beta Inhibition of EMCV-induced Cytopathy and Neutralization by Human IFN-beta  Antibody.

IFN‑ beta Inhibition of EMCV-induced Cytopathy and Neutralization by Human IFN-beta Antibody.

Recombinant Human IFN-beta (8499-IF) reduces the Encephalomyocarditis Virus (EMCV)-induced cytopathy in the HeLa human cervical epithelial carcinoma cell line in a dose-dependent manner (orange line), as measured by crystal violet staining. Inhibition of EMCV activity elicited by Recombinant Human IFN-beta (50 pg/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human IFN-beta Antigen Affinity-purified Polyclonal Antibody (Catalog # AF814). The ND50 is typically 0.100 - 1.00 µg/mL.

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.
