Recombinant Human Soluble IL-6 Receptor (s-IL-6R)

s-IL-6R Applications

Description :	The IL-6 receptor system consists of two chains, IL-6R alpha and gp130. The IL-6R alpha is the binding component specific 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 affinity 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. SBH Sciences' recombinant human sIL-6R alpha is a 37.6 kDa protein, consisting of the extra cellular domain of the sIL-6R alpha chain (338 amino acids).
Catalog #:	002-SIL6R
Source :	HEK 293 cells
Formulation :	The sterile filtered solution was lyophilized from 1 x PBS, pH 7.2.
Stability :	The lyophilized protein is stable for a few weeks at room temperature, but best stored at -200C. Reconstituted sIL-6R should be stored in working aliquots at -200C.
Purity :	Greater than 98% by SDS-PAGE and HPLC analyses. Endotoxin level is less than 0.1 ng per μg (1EU/μg).
Reconstitution :	We recommend a quick spin followed by reconstitution in 1 x PBS, pH 7.2 to a concentration of 0.1-1.0 mg/ml. This solution can then be diluted into other aqueous buffers and stored at 40C for 1 week or stored at -200C for futures use.
Biological Activity :	The ED50 as determined by it's ability to intensify the IL-6 induced growth inhibition of murine M1 cells is < 10.0 ng/ml, in the presence of 20 ng/ml of rhIL-6.
