Description
Human, Mouse, Rat IL-6 Receptor Recombinant Protein Lyophilized has been recombinantly produced in HEK293 cells.
IL-6 mediates its biological effects through the type I IL-6 receptor system that consists of two chains, IL-6Ralpha and gp130. While the IL-6Ralpha chain is the binding component specific to IL-6, the gp130 chain only transmits signals of IL-6 when bound to IL-6Ralpha. The gp130 can also transmit signals from LIF, OSM, CNTF, IL-11 and CT-1 in conjunction with other receptor subunits. The low-affinity binding site for IL-6 is composed of IL-6Ralpha alone. IL-6Ralpha is expressed in a wide range of cells, including T cells, fibroblasts and macrophages. Soluble IL-6Ralpha, which consists of only the extracellular domain of the IL-6Ralpha chain, acts as an agonist of IL-6 activity at low concentrations. Recombinant Human sIL-6Ralpha is a 37.6 kDa protein consisting of the extracellular domain of the IL-6Ralpha chain (339 amino acid residues)
