Active Recombinant Mouse IFNa4 protein, His-tagged

• Cat.No.: IFNa4-3275M
• Product Overview: Recombinant Mouse IFNa4 protein(NP_034634.1)(Met1-Glu186), fused with His tag, was expressed in HEK293.

Specification

• Species: Mouse
• Source: HEK293
• Tag: His
• Form: Lyophilized from sterile PBS, pH 7.4.Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.
• Bio-activity: Measured in antiviral assays using L929 cells infected with vesicular stomatitisvirus (VSV). The ED50 for this effect is 10-50 pg/mL.
• Molecular Mass: The recombinant mouse IFNA4 comprises 173 amino acids and has a predicted molecular mass of 20.2 kDa. The apparent molecular mass of the protein is approximately 22-27 kDa in SDS-PAGE under reducing conditions.
• Proteinlength: Met1-Glu186
• 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.
