Recombinant Human IL6R protein(Met1-Pro365), hFc-tagged

Specification :
| Source : HEK293 | Species : Human | Tag : C-hFc | Protein length : Met1-Pro365 | Form : Lyophilized from sterile PBS, pH 7.4. Normally 5 % – 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. | Bio-activity : 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. | Molecular Mass : The recombinant human IL6R consists of 584 amino acids and predicts a molecular mass of 65.3 kDa. As a result of glycosylation, it migrates as an approximately 70-100 kDa band in SDS-PAGE under reducing conditions. | Endotoxin : | Purity : > 95 % as determined by SDS-PAGE. | Storage : Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. | Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
