背景介绍 IL-6 is a member of a family of cytokines, which also includes LIF, CNTF, Oncostatin M, IL11, and CT- 1. All known members of the IL-6 cytokine family induce hepatic expression of acute phase proteins. IL-6 is produced by many different cell types. The main sources in vivo are stimulated monocytes, fibroblasts, and endothelial cells. Macrophages, T-cells and B-lymphocytes, granulocytes, smooth muscle cells, eosinophils, chondrocytes, osteoblasts, mast cells, glial cells, and keratinocytes also produce IL-6 after stimulation. The IL-6 receptor is expressed on T-cells, mitogen-activated B-cells, peripheral monocytes and some macrophage- and B-cell derived tumor cell types. It is not expressed in resting B-cells but in resting T-cells. The IL-6 receptor (CD126) is a strongly glycosylated protein of 80 kDa and a length of 449 amino acids. 产品介绍 Recombinant human IL-6 is a glycosylated disulfide-linked homodimeric protein consisting of 184 amino acid residues, and migrates as an approximately 20 kDa protein under non-reducing and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding Human Interleukin-6 mature chain was expressed in E. coli.
