Human IL-22 Antibody Summary

Species Reactivity
Human
Specificity
Detects human IL-22 in direct ELISAs. In direct ELISAs, this antibody shows 100% cross-reactivity with recombinant mouse IL‑22 and recombinant rat IL‑22 and no cross-reactivity with recombinant human IL‑10.
Source
Monoclonal Mouse IgG1 Clone # 142928
Purification
Protein A or G purified from hybridoma culture supernatant
Immunogen
E. coli-derived recombinant human IL-22
Ala34-Ile179
Accession # Q9GZX6
Formulation
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.
Endotoxin Level
<0.10 EU per 1 μg of the antibody by the LAL method.

Applications

Recommended Concentration
Sample
Neutralization
Measured by its ability to neutralize IL‑22-induced IL‑10 secretion in the COLO 205 human colorectal adenocarcinoma cell line. Nagalakshmi, M.L. et al. (2004) Intl. Immunopharmacol. 4:679. The Neutralization Dose (ND50) is typically 1-5 µg/mL in the presence of 1 ng/mL Recombinant Human IL‑22.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

IL‑10 Secretion Induced by IL‑22 and Neutralization by Human IL-22 Antibody. Recombinant Human IL-22 (Catalog # 782-IL) stimulates IL-10 secretion in the COLO 205 human colorectal adeno-carcinoma cell line in a dose-dependent manner (orange line), as measured by the Human IL-10 DuoSet ELISA Development Kit (Catalog # DY217B). IL-10 secretion elicited by Recombinant Human IL-22 (1 ng/mL) is neutralized (green line) by increasing concentrations of Human IL-22 Monoclonal Antibody (Catalog # MAB7821). The ND50 is typically 1-5 µg/mL.

Background: IL-22

Interleukin-22 (IL-22), also known as IL-10-related T cell-derived inducible factor (IL-TIF) was initially identified as a gene induced by IL-9 in mouse T cells and mast cells. Human IL-22 cDNA encodes a 179 amino acid (aa) residue protein with a putative 33 aa signal peptide that is cleaved to generate a 147 aa mature protein that shares approximately 79% and 22% aa sequence identity with mouse IL-22 and human IL-10, respectively. The human IL-22 gene is localized to chromosome 12q15. Although it exists as a single copy gene in human and in many mouse strains, the mouse IL-22 gene is duplicated in some mouse strains including C57B1/6, FVB and 129. The two mouse genes designated IL-TIF alpha and IL-TIF beta, share greater than 98% sequence homology in their coding region. IL-22 has been shown to activate STAT1 and STAT3 in several hepatoma cell lines and upregulate the production of acute phase proteins. IL-22 is produced by normal T cells upon anti-CD3 stimulation in humans. Mouse IL-22 expression is also induced in various organs upon lipopolysaccharide injection, suggesting that IL-22 may be involved in inflammatory responses. The functional IL-22 receptor complex consists of two receptor subunits, IL-22 R (previously an orphan receptor named CRF2-9) and IL-10R beta (previously known as CRF2-4), belonging to the class II cytokine receptor family.
