Human IL-29/IFN-lambda 1 Biotinylated Antibody Summary

Species Reactivity
Human
Specificity
Detects human IL‑29/IFN‑ lambda 1 in ELISAs and Western blots. In sandwich immunoassays, approximately 100% cross-reactivity with recombinant human (rh) IL-28B is observed, 35% cross-reactivity with rhIL-28A is observed and less than 0.2% cross‑reactivity with rhIFN‑ alpha A, rhIFN-alpha B2, rhIFN‑ alpha G, rhIFN alpha I, and rhIFN-beta 1A is observed. In Western blots, approximately 25% cross-reactivity with rhIL-28A and rhIL‑28B is observed.

Background: IL-29/IFN-lambda 1

IL-28A, IL-28B, and IL-29, also named interferon-lambda 2 (IFN-lambda 2), IFN-lambda 3, and IFN-lambda 1, respectively, are class II cytokine receptor ligands that are distantly related to members of the IL-10 family (11-13% aa sequence identity) and the type I IFN family (15-19% aa sequence identity) (1-3). The genes encoding these three cytokines are localized to chromosome 19 and each is composed of multiple exons. The exon organization of these genes is also found in the IL-10 family genes but is distinct from the type I IFNs, which are encoded within a single exon, The expression of IL-28A, B, and IL‑29 is induced by virus infection or double-stranded RNA. All three cytokines exert bioactivities that overlap those of type I IFNs, including antiviral activity and up-regulation of MHC class I antigen expression. The three proteins signal through the same heterodimeric receptor complex that is composed of the IL-10 receptor  beta (IL-10 R beta ) and a novel IL-28 receptor  alpha (IL-28 R alpha, also known as IFN-lambda R1). Ligand binding to the receptor complex induces Jak kinase activation and STAT1 and STAT2 tyrosine phosphorylation. The phosphorylated STAT1 and STAT2 complex with IFN-regulatory factor 9 (IRF-9) to form the IFN-stimulated regulatory factor 3 (ISGF-3) transcription factor complex that is translocated to the nucleus. ISGF-3 binds to the IFN-stimulated response element (ISRE) present in the regulatory region of the target genes. Human IL-29 cDNA encodes a 200 amino acid (aa) residue precursor protein with a putative 19 aa signal peptide and a 181 aa mature protein, which is a monomer in solution. It shares 67% and 69% aa sequence identity with human IL-28A and IL-28B, respectively.
