Background: 

The High Sensitivity Human IFN Beta Serum ELISA Kit has been developed to measure low/basal levels of human IFN-beta in autoimmune sera,  normal serum/ plasma or tissue culture media samples by sandwich enzyme linked immunosorbent assay (ELISA). This assay is suitable for measurement of trademarked therapeutic molecules in human serum samples. Researchers and clinical investigators examining a) the pharmacokinetics of IFN-beta molecules, b) IFN-beta as a biomarker, or c) IFN-beta as a pharmacodynamic marker of TLR agent or other immune response modifier activity will find this highly sensitive and specific assay to be an essential laboratory tool.

Interferon beta (IFN-beta) is part of the first wave of cytokine response in cells. Pathogen infection can result in the activation of interferon regulatory factor 3 (IRF3) that functions in trans to activate IFN beta gene transcription. IFN-beta is biologically unique when compared to other interferons and studies have shown that IFN-beta has overlapping and distinct gene expression patterns as compared to IFN-alpha. It appears that IFN-beta binds to the Type I IFN receptor with higher affinity than the other Type I IFNs and it may also regulate receptor internalization in a different manner. Additionally, IFN-beta has long been known to inhibit viral replication as part of the body’s innate antiviral response and is used as a therapeutic for treatment of multiple sclerosis and some tumors.
