Interferon ELISA kits are assays designed to detect the group of proteins known as interferons (IFNs). They are a family of cytokines involved in inflammation and immunomodulation. There are two main types of IFNs – IFN type I, which consists of IFN-α, IFN-β, IFN-ε, IFN-κ, and IFN-ω, and IFN type II, which consists of IFN-γ in humans. IFNs play a vital role in the protection against viral infection and replication. They also activate many other molecules of the immune system such as natural killer cells and macrophages.
