Purity: > 90% by SDS - PAGE Format: Liquid. In Phosphate Buffered Saline (pH 7.4) containing 10% glycerol.. IL6R, also known as interleukin-6 receptor subunit alpha isoform 1, is a type I cytokine receptor. It is a potent pleiotropic cytokine that regulates cell growth and differentiation and plays an important role in immune response. It has a modular build of several immunoglobulin-like and fibronectin type III-like domains. The low concentration of a soluble form of IL-6 receptor (sIL-6R) acts as an agonist of IL-6 activity. In the IL-6R/CD126/IL6R system, both a membrane-bound IL-6R and a sIL-6R protein are able to mediate IL-6 signals into the cells through the interaction of gp130. It is implicated in the pathogenesis of many diseases, such as multiple myeloma, autoimmune diseases and prostate cancer. Recombinant human IL6R, fused to His-tag at C-terminus, was expressed in insect cell and purified by using conventional chromatography techniques.
