Chimeric Use Statement:This chimeric mouse antibody was made using the variable domain sequences of the original Human IgG1 format, for improved compatibility with existing reagents, assays and techniques.
Specificity Statement:This antibody binds an epitope at the surface formed by helices A and D of human interleukin-13. This epitope overlaps with the IL-4Ralpha/IL-13Ralpha1 receptor-binding site, which explains the neutralizing effect of CNTO607. IL-13 is a cytokine secreted by T helper type 2 (Th2) cells, CD4 cells, natural killer T cell, mast cells, basophils, eosinophils and nuocytes. It inhibits the production of inflammatory cytokines (IL-1, IL-6, TNF, IL-8) by LPS-stimulated monocytes. It synergizes with IL2 in regulating interferon-gamma synthesis. It is a mediator of allergic inflammation and different diseases including asthma.
Application Notes:The original IgG1 version of this antibody binds human IL-13 with an affinity of 18pM and prevents binding of IL-13 to both IL-13Rα1 and IL-4Rα. This antibody can bind native wild type and recombinant human IL-13 in an ELISA (PMID: 19361524). This antibody is capable of neutralizing IL13 activity in the TF-1 and in the IL-13Rα1 receptor binding assay (US20080044420). This antibody has the tendency to self associate. The IgG1 version of this antibody can be concentrated to ∼13 mg/ml before irreversible precipitation occurs (PMID: 22915597). The relative binding affinity of the IgG1 version of this antibody was determined to be 18.4 pM (PMID: 22915597).
