Applications

Recommended Concentration

Sample

ELISA

This antibody functions as an ELISA detection antibody when paired with Mouse Anti-Human IFN‑ beta Monoclonal Antibody (Catalog # MAB8144).

This product is intended for assay development on various assay platforms requiring antibody pairs. We recommend the Human IFN-beta DuoSet ELISA Kit (Catalog # DY814-05) for convenient development of a sandwich ELISA or the Human IFN-beta Quantikine ELISA Kit (Catalog # DIFNB0) for a complete optimized ELISA.

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.

Human IFN‑ beta ELISA Standard Curve. Recombinant Human IFN-beta protein was serially diluted 2-fold and captured by Mouse Anti-Human IFN-beta Monoclonal Antibody (Catalog # MAB8144) coated on a Clear Polystyrene Microplate (Catalog # DY990). Mouse Anti-Human IFN-beta Monoclonal Antibody (Catalog # MAB8143) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998) followed by Substrate Solution (Catalog # DY999) and stopping the enzymatic reaction with Stop Solution (Catalog # DY994).

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.
