Tech Info / Data

Image of global human interferon alpha-specific signals in autoimmune sera (n=26) using PBL's High Sensitivity Human Interferon Alpha All Subtype ELISA kit

This high sensitivity Human IFN Alpha ELISA kit is designed to provide accurate low pg/ml measurement of ALL human interferon alpha subtypes in autoimmune sera, normal serum, and tissue culture media (TCM). This unique feature provides an improved view of global IFN-alpha production in sample analysis. 

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.
