Tech Info / Data

Human IFN alpha 2a extended range curve from 156 to 5000 pg/ml using PBL Human Interferon Alpha Multi-Subtype ELISA (41105)

The VeriKine Human IFN-α Multi-Subtype ELISA kit is specifically formulated to detect 14 out of 15 identified human IFN-α subtypes/alleles in media using a sandwich immunoassay. They are: IFN-αA, IFN-α2, IFN-αD, IFN-αB2, IFN-αC, IFN-αG, IFN-αH, IFN-αI, IFN-αJ1, IFN-αK, IFN-α1, IFN-α4a, IFN-α4b, and IFN-αWA. 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 initially characterized by their ability to inhibit viral infection. Generation of type I IFNs occurs downstream of a multitude of immunologic stimuli and can be either an indicator of host defense or an indicator of autoimmunity. In addition to their antiviral properties, IFNs have also been shown to exhibit anti-proliferative, immunomodulatory, and many other activities.

In humans, Interferon Alpha (IFN-alpha) is a family comprised of more than 12 homologous protein subtypes that exhibit diverse biologic activities. This group of proteins 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. At least one subtype is used as a therapeutic, as a readout of drug efficacy in clinical trials, and as a marker of pathology in human clinical and preclinical studies. Elucidating the functional significances of various IFN-alpha subtypes can lead to further refinement of current interferon based therapeutic applications.
