PBL Assay Science offers human IFN-Beta (interferon beta) in three formats: two mammalian (CHO)-expressed, glycosylated versions (one carrier-free liquid, one frozen with a carrier protein), and one E. coli-expressed, non-glycosylated version. Picking the right one helps you avoid carrier-protein interference in sensitive assays, match the glycosylation state your study requires, and get the sample volume and storage conditions that fit your workflow.
Human IFN-Beta Biology
IFN-beta production and secretion are triggered mainly through pattern recognition receptors, including Toll-like receptors (TLRs) and RIG-I-like receptors (RLRs). It's one of the first cytokines released after a cell detects infection: pathogen sensing activates interferon regulatory factor 3 (IRF3), which turns on IFN-beta gene transcription. IFN-beta stands apart from other type I interferons in several ways. Its gene expression profile overlaps with, but isn't identical to, IFN-alpha's. It also binds the type I IFN receptor (IFNAR) with higher affinity than other type I interferons and may drive receptor internalization differently as a result.
