Tech Info / Data

Typical human IFN alpha 2a extended range curve from 156 to 5000 pg/ml using PBL Human Interferon Alpha ELISA (41100)

The VeriKine Human Interferon Alpha ELISA Kit has been developed to quantify levels of human IFN-alpha in cell or tissue culture media using a sandwich enzyme linked immunoassay (ELISA). The kit is based on an ELISA with anti-detection antibody conjugated to horseradish peroxidase (HRP). Tetramethyl-benzidine (TMB) is the substrate. The assay is based on the international reference standard for human interferon alpha (Hu-IFN-α) provided by the National Institutes of Health.

Interferons (IFNs) are a family of mammalian cytokines produced by a variety of cells in response to viral infection, immunity stimulators and chemical inducers. They exhibit a wide range of biological activities that include antiviral, anti-proliferative and immunomodulatory functions. When IFN interacts with its cognate receptor, a signal is rapidly transmitted within the cell, often producing an antiviral state. The primary signal transduction cascade promoted by type I IFNs is the JAK1-STAT pathway. Activation of this signal transduction pathway leads to increased gene expression including (2’-5’) oligoadenylate synthetases, Mx proteins, and protein kinase R (PKR) that protect the cell from viral infection.

Interferon Alpha (IFN-alpha), a type I interferon, was one of the first FDA approved biotherapeutic treatments. Accurate measurement of IFN-alpha in cell or tissue culture media allows evaluation of basic immune responses as well as assessing the potency of Toll-Like Receptor (TLR) agonist-based therapeutics in vitro
