Name :
Recombinant Human IL-6 Protein
Biological Activity :
Background :
Interleukin-6 (IL-6) is a multifunctional α-helical cytokine that regulates cell growth and differentiation of various tissues, which is known particularly for its role in the immune response and acute phase reactions. IL-6 protein is secreted by a variety of cell types including T cells and macrophages as a phosphorylated and variably glycosylated molecule. It exerts actions through its heterodimeric receptor composed of IL-6R that lacks the tyrosine/kinase domain and binds IL-6 with low affinity, and ubiquitously expressed glycoprotein 130 (gp130) that binds the IL-6. IL-6R complex with high affinity and thus transduces signals. IL-6 is also involved in hematopoiesis, bone metabolism, and cancer progression, and has been defined as an essential role in directing the transition from innate to acquired immunity.

Biological Activity :
1. Immobilized Human IL-6 (Cat:10395-HNAE) at 2 μg/mL (100 μL/well) can bind Human IL-6R hFc(Cat:10398-H02H), the EC50 of Human IL-6R hFc(Cat:10398-H02H) is 3.0-10.0 ng/mL.2. Measured in a cell proliferation assay using TF-1 human erythroleukemic cells. The ED50 for this effect is 0.1-0.8 ng/mL.3.Loaded Recombinant Human IL-6R Protein, His Tag (Cat. No. 10398-H08H) on His1K Biosensor, can bind Recombinant Human IL-6 Protein, no Tag (Cat. No. 10395-HNAE) with an affinity constant of 0.165µM as determined in BLI assay (Sartorius Octet RED384)(Routinely tested).
