背景介绍 IL-11 is secreted by bone marrow stromal cells (fibroblasts)and is produced also by a number of mesenchymal cells. The IL-11 receptor (alpha chain) utilizes gp130 as its signal transducer, which is also a component of other cytokine receptors. The alpha chain of the IL-11 receptor has been identified independently as Etl2. IL-11 promotes primary and secondary immune responses in vitro and in vivo and modulates antigen-specific antibody reactions. IL-11 promotes the proliferation of IL-6 dependent plasmacytoma cell lines in the presence of neutralizing IL-6 antibodies. IL-11 also stimulates the T-cell dependent development of IgG-secreting B-cells in spleen cell cultures. IL-11 inhibits the differentiation of pre- adipocytes. It induces the synthesis of some acute phase proteins by hepatocytes. 产品介绍 Recombinant IL-11 is a disulfide-linked monomer protein consisting of 179 amino acid residues, and migrates as an approximately 19 kDa protein under non-reducing conditions and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding human Interleukin-11 mature chain was expressed in E. coli.
