Human IFN-Beta ELISA Kit, High Sensitivity (Serum, Plasma, TCM)

Catalog Number: 41415

This Human IFN-Beta ELISA measures interferon beta levels in human serum, plasma, and tissue culture samples with 1.2 pg/ml LLOQ sensitivity. This kit has been validated for the measurement of IFN-Beta in autoimmune serum and of trademarked IFN-Beta 1a and IFN-Beta 1b therapeutic molecules in human serum. There is no detection inhibition by 3-log excess of soluble IFNAR2 protein.

The VeriKine-HS Human IFN-Beta ELISA Kit is designed to measure low or basal levels of Human IFN-Beta in autoimmune disease sera, healthy serum/plasma, or tissue culture media samples with 1.2 pg/ml LLOQ sensitivity.

 

This assay is suitable for the 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 immunoassay to be an essential laboratory tool.

 

*For a TCM-compatible ELISA, we recommend our Human IFN-Beta ELISA Kit, High Sensitivity (Cat. No. 41435-1).

Background

 

Interferon beta (IFN-Beta, IFNb) is part of the first wave of cytokine response in cells. Pathogen infection can result in the activation of interferon regulatory factor 3 (IRF3) which 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 the treatment of Multiple Sclerosis (MS) and some tumors.
