Name :
Recombinant Human IL-6R Protein (ECD, hFc Tag)

Biological Activity :

Background :
Interleukin 6 receptor (IL-6R) also known as CD126 (Cluster of Differentiation 126) is a type I cytokine receptor. 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 can mediate IL-6 signals into the cells through the interaction of gp130. The resulting IL-6/sIL-6R protein complex is also capable of binding to gp130 and inducing intracellular signaling. Through this so-called ‘trans-signaling’ mechanism, IL-6 can stimulate cells that lack an endogenous mIL-6R. High levels of IL-6 and SIL-6R have been reported in several chronic inflammatory and autoimmune diseases as well as in cancer. Cancer Immunotherapy Immune Checkpoint Immunotherapy Targeted Therapy

Biological Activity :
1.Measured by its ability to enhance the activity of IL6 on M1 mouse myeloid leukemia cells. The ED50 for this effect is typically 30-125 ng/mL in the presence of 100 ng/mL of recombinant human IL6.2.Loaded Recombinant Human IL-6R Protein, hFc Tag (Cat. No. 10398-H02H) on ProA Biosensor, can bind Recombinant Human IL-6 Protein, no Tag (Cat. No. 10395-HNAE) with an affinity constant of 0.51µM as determined in BLI assay (Sartorius Octet RED384) (Routinely tested).3.Immobilized Recombinant Human IL6 / Interleukin-6 Protein (Cat: 10395-HNAE) at 2μg/mL (100μL/well) can bind Recombinant Human IL-6R / CD126 Protein (ECD, Fc Tag) (Cat: 10398-H02H), the EC50 is 5-15 ng/mL.
