Discription：Murine Interleukin-13 （IL-13） is expressed by the IL13 gene located on the chromosome 11 and secreted by many cell types, especially T helper type 2 （Th2） cells. Targeted deletion of IL-13 in mice resulted in impaired Th2 cell development and indicated an important role for IL-13 in the expulsion of gastrointestinal parasites. IL-13 exerts anti-inflammatory effects on monocytes and macrophages and it inhibits the expression of inflammatory cytokines such as IL-1β, TNF-α, IL-6 and IL-8. IL-13 has also been shown to enhance B cell proliferation and to induce isotype switching, resulting in increased production of IgE. Blocking of IL-13 activity inhibits the pathophysiology of asthma. Human, mouse and rat IL-13 share low homology, but have cross species activity. Recombinant Murine IL-13 is a 12.3kDa protein consisting of 111 amino acid
