The VeriKine Human IFN-Alpha Multi-Subtype ELISA kit is specifically formulated to detect 14 out of 15 identified human IFN-Alpha subtypes/alleles in media using a sandwich immunoassay. They are: IFN-AlphaA, IFN-Alpha2, IFN-AlphaD, IFN-AlphaB2, IFN-AlphaC, IFN-AlphaG, IFN-AlphaH, IFN-AlphaI, IFN-AlphaJ1, IFN-AlphaK, IFN-Alpha1, IFN-Alpha4a, IFN-Alpha4b, and IFN-AlphaWA.
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 IFN-Alpha provided by the National Institutes of Health.
*For global subtype detection and additional sensitivity, we recommend our Human IFN-Alpha All-Subtype TCM ELISA Kit, High Sensitivity (Cat. No. 41135-1).
*For global subtype detection, additional sensitivity, and complex biological matrices such as plasma and serum, we recommend our Human IFN-Alpha All-Subtype ELISA Kit, High Sensitivity (Cat. No. 41115-1).

Tips, Tools and Troubleshooting:
Interferons (IFNs) are a family of mammalian cytokines initially characterized by their ability to inhibit viral infection. They are synthesized and secreted by most cell types in response to pathogens. In addition to their antiviral properties, IFNs have also been shown to exhibit anti-proliferative, immunomodulatory, and many other activities.
In humans, IFN-α consists of a group of proteins that are greater than 85% homologous by amino acid sequence. Numerous individual human IFN-α subtypes have been identified; many display different properties. It remains unclear why there are multiple IFN-α subtypes. A variety of studies suggested they possess overlapping but also unique sets of biological activities.
