• Specifications

  • Species of Origin

    Human

    Expression system

    Escherichia coli

  • Affinity Tag

    His Tag (N-term)

    Buffer

    Lyophilized from a 0.2 µm filtered solution of 500 mM NaCl, 2.7 mM KCl, 10 mM Na2HPO4, and 1.8 mM KH2PO4, pH7.4.

  • Purity

    >95% as determined by SDS-PAGE analysis.

    Molecular weight

    The protein has a calculated MW of 20.19 kDa.
    The protein migrates as 19 kDa under reducing condition (SDS-PAGE analysis).

  • Activity

    Measure by its ability to inhibit IL-8 secretion in human PBMCs in the presence of LPS. The ED₅₀ for this effect is <1.12 μg/mL.

    Endotoxin level

    <0.1 EU per 1 μg of the protein by the LAL method.

  • Form

    Lyophilized

• Background

  • Background

    Interferon-alpha 1a (IFN-alpha 1a) is a leukocyte interferon, which is a variant of Interferon-alpha. IFN-alpha 1a is a 19.5kDa protein containing 167 amino acid residues. It could bind the interferon receptors that activates the signal transduction of immune responses through the Jak/STAT pathway in leukocytes and lymphoblastoid cells.

    Synonyms

  • Uniprot ID

    P01562

    Sequence Note

    Cys24-Glu189

• Instruction

  • Reconstitution

    It is recommended to reconstitute the lyophilized protein in sterile H₂O to a concentration of 200 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.

    Shipping

    The product is shipped with polar packs. Upon receipt, store it immediately at -20°C or lower for long term storage.

  • Stability & Storage

    This product is stable after storage at:

    • -20°C for 12 months in lyophilized state from date of receipt.
    • -20°C or -80°C for 1 month under sterile conditions after reconstitution.

    Avoid repeated freeze/thaw cycles.
