背景介绍 IL-12 is secreted by peripheral lymphocytes after induction. It is produced mainly by B-cells and to a lesser extent by T-cells. The most powerful inducers of IL-12 are bacteria, bacterial products, and parasites. IL-12 is produced after stimulation with phorbol esters or calcium ionophore by human B-lymphoblastoid cells. The IL-12 receptor, CD212, appears to be a single protein of approximately 110 kDa. Up to 1000-9000 high affinity IL-12 receptors/cell are expressed on peripheral blood mononuclear cells activated by various mitogens for T-cells or by IL2. IL-12 receptors are present on activated T-cells expressing CD4 and CD8 and on activated CD56(+) natural killer cells. Resting peripheral blood mononuclear cells, tonsillar B-cells, or tonsillar B-cells activated by anti-IgM/Dx, anti-IgM/Dx + IL-2, or SAC + IL-2 do not express the receptor. Human IL-12 is not active in murine lymphocytes. Hybrid heterodimers consisting of murine p35 and human p40 subunits retain bioactivity on murine cells, however, the combination of human p35 and murine p40 is completely inactive on murine cells. Murine IL-12 is active on both murine and human lymphocytes. 产品介绍 Recombinant Interleukin-12 is a disulfide-linked heterpdimer protein consisting of 306 amino acid residue p40 subunit and a 197 amino acid residue p35 subunit, and migrates due to glycosylation as an approximately 75 kDa protein under non-reducing and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding human Interleukin-12 mature chain was expressed in Chinese Hamster Ovary (CHO) cells.

询价背景介绍 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 mouse Interleukin-11 mature chain was expressed in E. coli.

询价背景介绍 IL-10 is produced by mouse Th2-cells following their stimulation by lectins. The main source for B-cell derived IL-10 in mice are Ly1 B-cells that express CD5 (Ly1) and CD11. In humans IL-10 is produced by activated CD8(+) peripheral blood T-cells, by T-helper CD4(+) T-cell clones after both antigen-specific and polyclonal activation, by B- cell lymphomas, and by monocytes following cell activation by bacterial lipopolysaccharides and mast cells. IL-10 is a homodimeric protein with subunits having a length of 160 amino acids. Human Interleukin-10 shows 73% amino acid homology with mouse Interleukin-10. The murine IL-10 receptor has been cloned. This receptor is a protein of approximately 110 kDa that binds murine IL-10 specifically. This receptor is structurally related to receptors for IFN. The CD nomenclature for this receptor is CDw210. IL-10 inhibits the synthesis of a number of cytokines such as IFN-gamma, IL-2 and TNF-beta in Th1 T-helper subpopulations of T-cells but not of Th2 T-helper cells. This activity is antagonized by IL-4. The inhibitory effect on IFN- gamma production is indirect and appears to be the result of a suppression of IL-12 synthesis by accessory cells. In the human system, IL-10 is produced by, and down-regulates the function of Th1 and Th2 cells. 产品介绍 Recombinant Rat Interleukin-10 is a disulfide-linked monomer protein consisting of 161 amino acid residues, and migrates as an approximately 19 kDa protein under non-reducing and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding rat Interleukin-10 mature chain was expressed in E. coli.
