      Interferon-alpha (IFN-alpha), also known as leukocyte interferon, represents a group of related but distinct proteins that share over 95% amino acid sequence homology. They are members of the type I interferon family which share a common cell surface receptor composed of two subunits, a 100 kDa ligand-binding subunit (IFN-alpha R2) and a 125 kDa ligand binding and signal transduction subunit (IFN-alpha R1) that is involved both in ligand binding and signal transduction. IFN-alpha has both anti-viral and immunomodulatory activities on target cells.

      None

      Physical Appearance

      Sterile Filtered White lyophilized (freeze-dried) powder.

      Purity

      > 97% by SDS-PAGE and HPLC analyses.

      Biological Activity

      Fully biologically active when compared to standard. The activity is determined by the cytopathic effect inhibition assay.

      Endotoxin

      < 0.1 EU/μg of protein as determined by LAL method.

      Formulation

      Lyophilized from a 0.2 µm filtered solution in PBS, pH 7.4, with 0.02 % Tween-20.

      Reconstitution

      We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions.

       

      Shipping and Storage

      The products are shipped with ice pack and can be stored at -20℃ to -80℃ for 1 year.

      Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.

       

      Cautions

      1. Avoid repeated freeze-thaw cycles.

      2. For your safety and health, please wear lab coats and disposable gloves for operation.

      3. For research use only.
