Active Recombinant Rat Ifna4 protein, hFc-tagged

• Cat.No.: Ifna4-7447R
• Product Overview: Recombinant Rat Ifna4 protein(D3ZFH0)(Cys24-Lys189), fused with hFc tag, was expressed in HEK293.

Specification

• Species: Rat
• Source: HEK293
• Tag: Fc
• Protein Length: Cys24-Lys189
• Form: Lyophilized from sterile PBS, pH 7.4Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Bio-activity: Measured in antiviral assay using L929 cells infected with vesicular stomatitisvirus (VSV).The ED50 for this effect is typically 0.5-4 μg/mL.
• Molecular Mass: The recombinant rat IFNA4 comprises 426 amino acids and predicts a molecular mass of 47.5 kDa. The apparent molecular mass of the recombinant protein is approximately 48 kDa in SDS-PAGE under reducing conditions 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.
