Bioactivity

1. Immobilized Recombinant Human IL6 / Interleukin-6 Protein (Cat: 10395-HNAE) at 2μg/mL (100μL/well) can bind Recombinant Human IL6R / CD126 Protein (His Tag) (Cat: 10398-H08H), the EC50 is 8-24 ng/mL. 2. Measured by its ability to enhance the IL6 activity on M1 mouse myeloid leukemia cells. The ED50 for this effect is typically 20-80 ng/mL. 3. Using the Octet RED System, the affinity constant (Kd) of IL-6R Protein, Human, Recombinant (His Tag) (Cat. 10398-H08H) bound Anti-IL6R Antibody (Cat. 10398-MM08) was 0.1 nM. 4. Loaded Recombinant Human IL-6R Protein, His Tag (Cat. No. 10398-H08H) on HIS1K Biosensor, can bind Recombinant Human IL-6 Protein (Cat. No. 10395-HNAE) with an affinity constant of 75.9 nM as determined in BLI assay (Sartorius Octet RED384) (Routinely tested) .

Function

Met1-Pro365

Molecular Weight

The soluble form of recombinant human IL6R consists of 357 amino acids and has a predicted molecular mass of 40 kDa. In SDS-PAGE under reducing conditions, it migrates with an apparent molecular mass of 60-65 kDa due to glycosylation.
