Description: Human IFN-α1 is a type I interferon previously known as B-cell interferon, leukocyte interferon, lymphoblast interferon, and pH2-stable interferon. IFN-α1 is one of at least 23 different known variants of IFN-α. The individual proteins have molecular masses between 19-26 kDa and consist of proteins with lengths of 156-166 and 172 amino acids. The IFN-α forms are produced by monocytes/macrophages, lymphoblastoid cells, fibroblasts, and other cell types following induction by viruses, nucleic acids, glucocorticoid hormones, and low-molecular weight substances (n-butyrate, 5-bromodeoxyuridine). Human IFN-α1 promotes antiviral, antiparasitic, and antiproliferative activities.
