Anti-Human IL-6 R - Biotin (I-761-50ug)

IL-6 mediates its biological effects through the type I IL-6 receptor system that consists of two chains, IL-6R alpha and gp130. The IL-6R alpha chain is the binding component specific to IL-6; while the gp130 only transmits signals of IL-6 when bound to IL-6R alpha. The gp130 also can 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-6R alpha alone. IL-6R alpha is expressed in a wide range of cells including T cells, fibroblasts and macrophages. Soluble IL-6R alpha which consists of only the extracellular domain of the IL-6R alpha chain, acts as an agonist of IL-6 activity at low concentrations.
