ABOUT
Neutralizing monoclonal antibody against human interleukin 28B
Anti-hIL-28b-IgG (clone 18F4) is a monoclonal antibody (mAb) specific for human interleukin 28B (hIL-28B). It is produced in hybridomas and purified by affinity chromatography. This antibody has been selected for its ability to efficiently neutralize the biological activity of hIL-28B. IL-28B (also known as interferon lambda 3) is a member of the type III interferon (IFN lambda) cytokine family that exhibits several common features with type I IFNs: antiviral activity and antitumor activity [1, 2].
Key features:
- A potent and specific neutralizing mAb against hIL-28B
- Provided azide-free
- Each lot is functionally tested

Details
The IFN-λ family is essential to the antiviral response at epithelial barriers [1,2]. In humans, this family comprises four distinct proteins called IFN-λ1 (interleukin-29, IL-29), IFN-λ2 (IL-28A), IFN-λ3 (IL-28B), and the poorly secreted IFN-λ4. In mice, two functional orthologs (IL-28A and IL-28B) have been described. IFN-λs are produced when a viral infection is sensed by pattern recognition receptors. IFN-λs bind to a heterodimeric receptor formed by the assembly of IFNLR1 and IL10Rβ. This leads to the recruitment of the Janus kinases, JAK1 and TyK2, and phosphorylation of STAT1 and STAT2, which then dimerize and interact with IFN regulatory factor 9 (IRF9), forming the ISGF3 complex. ISGF3 binds to IFN-stimulated response elements (ISRE) in the promoters of IFN-stimulated genes (ISG) to regulate their expression.
