The Interleukin-6 receptor (IL-6R) consists of an 80-kDa IL-6 binding protein (α chain) (CD126) and gp130. The alpha-chain CD126 is a glycoprotein that contains the ligand-binding site. The human IL-6R protein contains 468 amino acids, which includes a signal peptide, an extracellular region, a transmembrane domain, and a short cytoplasmic domain of 19, 339, 28, and 82 amino acids, respectively. IL-6R are present on several types of tumor cells, including multiple myeloma, hepatocellular carcinoma, prostate carcinoma , and epidermoid carcinoma. The IL-6/IL-6R signal pathway promotes the tumor growth in various cancers, especially for glioma. Hence, IL-6R not only can be used as a target site for transporting drugs, but also as a therapeutic site. Primary human cartilage cells express IL-6R, which is further induced in the presence of IL-6. This makes cartilage cells direct targets or effectors of IL-6.
Protein A Chip captured IL-6R alpha/CD126 Fc Chimera, Human (Cat. No. UA010448), can bind IL-6, Human (Cat. No. UA040052) with an affinity constant of 8.51 nM as determined in SPR assay.
Immobilized IL-6, Human (Cat. No. UA040052) at 5.0μg/mL (100μL/well) can bind IL-6R alpha/CD126 Fc Chimera, Human (Cat. No. UA010448) with EC50 of 3.04-3.92ng/ml.
