General description

Interleukin-13 (IL-13) is a cytokine produced by Th2 cells and mediates the production of immunoglobulins, B cell proliferation and differentiation of cells of the monocytic lineage. The interaction of IL-13 with its receptor triggers responses via the STAT-6 pathway and results in antibody-mediated responses, eosinophil recruitment in lungs, airway remodelling, mucus overproduction, secretion of matrix metalloproteinases (MMP)-9 and MMP-12 and IgE production. The other signaling axis that is mediated by IL-13 is the EGFR-TGF-α pathway that induces proliferation of epithelial cells. Elevated IL-13 has been associated with the symptoms of asthma and is detected in elevated levels in the airways and sputum of asthma patients
Monoclonal Anti-Mouse Interleukin-13 recognizes recombinant mouse IL-13.


The biological activity is measured by its ability to neutralize recombinant mouse IL-13.


purified recombinant mouse IL-13 expressed in E. coli.


Monoclonal anti-mouse interleukin-13 may be used in neutralization assays at a working concentration range of 03.-0.8 μg/ml. For immunoblotting a concentration of 1-2 μg/ml may be used. For ELISA a working concentration of 2-4 μg/ml is recommended.

Physical form

Lyophilized from a 0.2 μm filtered solution in phosphate buffered saline with 5% trehalose.
