Medchemexpress LLC IFN-beta Human CHO 2ug
IFN-beta is a secretory cytokine produced by cells under viral infection or nucleic acid stimulation IFN binds to cell surface heterodimeric receptors (IFNAR1/IFNAR2) activates the JAK-STAT signaling pathway and induces the expression of interferon-stimulated genes (ISGs) (such as PKR 2 5 -OAS) IFN-beta inhibits viral proliferation regulates immune responses (such as inhibiting Th1 cell polarization reducing pro-inflammatory cytokine secretion) inhibits the proliferation of vascular smooth muscle cells and tumor cells IFN-beta has anti-atherosclerotic and vascular remodeling effects IFN-beta Protein Human (CHO) is a recombinant interferon-beta protein (CHO) expressed by CHO without a tag
