Specificity
This antibody recognises interferon beta (IFN-beta), a 22 kDa member of the type I alpha/beta interferon family. IFN beta, initially described as fibroblast interferon, is produced predominantly by fibroblasts and some epithelial cells. Type 1 interferons are produced primarily in response to viral infections as part of the host immune response and can also inhibit the development of tumors. IFN-beta is involved in the regulation of non-specific humoral immune responses and responses against viral infections.
