Technical Data
CD126 (Interleukin 6 Receptor, IL-6R)
The IL-6 receptor system consists of two chains, IL-6R alpha and gp130. The IL-6R alpha is the binding component speci c to the IL-6, but does not transduce a signal alone. On the contrary, gp130 transmits signals not only of IL-6, but also IL-6 related cytokines, i.e. LIF, OSM, CNTF, IL-11 and CT-1. The low af nity binding sites for IL-6, is composed of IL-6R alpha alone. At low concentrations, soluble IL-6R alpha acts as an agonist of IL-6 activity.

Suitable for use in Flow Cytometry, Immunohistochemistry, ELISA, Immunoprecipitation and Inhibition assays. Other applications not tested.

CHO cells transfected with cDNA of the IL-6 receptor.
Purified by Ion Exchange chromatography.
Supplied as a liquid in PBS, pH 7.4, 0.09% sodium azide. Removal of sodium azide is recommended prior to use in functional assays.
Recognizes soluble and membranous human IL-6R. This antibody has been shown to inhibit IL-6 mediated proliferation of XG-1 cells. It partially blocks binding of IL-6 to its receptor.
Intended for research use only. Not for use in human, therapeutic, or diagnostic applications.
