Acitve Recombinant Human IL6ST protein(Met1-Ile618), His&hFc-tagged

• Cat.No.: IL6ST-1380H
• Product Overview: Recombinant Human IL6ST (NP_002175.2)(Met 1-Ile 618) was expressed in HEK293, fused with the C-terminal polyhistidine-tagged Fc region of human IgG1 at the C-terminus.

Specification

• Source: HEK293
• Species: Human
• Tag: C-His&hFc
• Protein length: Met1-Ile618
• 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 inhibit the IL-6Rα enhancement of IL-6 activity on M1 Mouse myeloid leukemia cell. The ED50 for this effect is typically 0.2-0.8 μg/mL in the presence of 50 ng/mL recombinant Human IL-6sR and 100 ng/mL recombinant Human IL-6.
• Molecular Mass: The recombinant Human IL6ST/Fc is a disulfide-linked homodimer after removal of the signal peptide. The reduced monomer consists of 844 amino acids and has a predicted molecular mass of 96 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh IL6ST/Fc monomer is approximately 125-140 kDa due to glycosylation.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Purity: > 90 % 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.
