Recombinant Human IFNB1 protein(Met1-Asn187), hFc-tagged

• Cat.No.: IFNB1-14H
• Product Overview: Recombinant Human IFNβ (NP_002167.1) (Met 1-Asn 187) was expressed in HEK293, fused with the Fc region of Human IgG1 at the C-terminus.

Specification

• Species: Human
• Source: HEK293
• Tag: Fc
• Protein Length: 1-187 a.a.
• 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 in antiviral assays using WISH human amnion cells infected with vesicular stomatitis virus (VSV). The ED50 for this effect is 0.08-0.8 ng/mL.
• Molecular Mass: The recombinant human IFNβ/Fc is a disulfide-linked homodimeric protein. The reduced monomer consists of 404 amino acids and has a predicted molecular mass of 46.7 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh IFNβ/Fc monomer is approximately 52 kDa due to glycosylation.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• 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.
