Human IL-29/IFN-lambda 1 Antibody Summary

Species Reactivity
Human
Specificity
Detects human IL-29/IFN-lambda 1 in ELISAs. In sandwich immunoassays, 100% cross-reactivity with recombinant human (rh) IL-28B/IFN-lambda 3 and 20% with rhIL‑28A is observed. No cross-reactivity or interference was observed with rhIFN-alpha A, rhIFN-alpha B2, rhIFN-alpha G, rhIFN-alpha I, or rhIFN‑ beta 1A.

Use in combination with:

Detection Reagent: Human IL‑29/IFN‑ lambda 1 Biotinylated Antibody (Catalog # BAF1598)

Standard: Recombinant Human IL-29/IFN-lambda 1 Protein (Catalog # 1598-IL)

Neutralization
Measured by its ability to neutralize IL‑29/IFN‑ lambda 1 inhibition of EMCV-induced cytopathy in the HepG2 human hepatocellular carcinoma cell line. Sheppard, P. et al. (2003) Nat. Immunol. 4:63. The Neutralization Dose (ND50) is typically 1-4 µg/mL in the presence of 40 ng/mL Recombinant Human IL‑29/IFN‑ lambda 1.

IL‑29/IFN‑ lambda 1 Inhibition of EMCV‑induced Cytopathy and Neutralization by Human IL‑29/IFN‑ lambda 1 Antibody. Recombinant Human IL-29/IFN-lambda 1 (Catalog # 1598-IL) reduces the Encephalomyocarditis Virus (EMCV)-induced cytopathy in the HepG2 human hepatocellular carcinoma cell line in a dose-dependent manner (orange line). Inhibition of EMCV activity elicited by Recombinant Human IL-29/IFN-lambda 1 (40 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anri-Human IL-29/IFN-lambda 1 Monoclonal Antibody (Catalog # MAB15981). The ND50 is typically 1-4 µg/mL.

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.
