• Specifications

  • Species of Origin

    Human

    Expression system

    Escherichia coli

  • Affinity Tag

    His Tag (C-term)

    Buffer

    Lyophilized from a 0.2 µm filtered solution of PBS, pH 8.0.

  • Purity

    >98% as determined by SDS-PAGE analysis.

    Molecular weight

    The protein has a calculated MW of 20.60 kDa.
    The protein migrates as 20 kDa under reducing condition (SDS-PAGE analysis).

  • Activity

    Measure by its ability to protect HepG2 cells infected with encephalomyocarditis (EMC) virus. The ED₅₀ for this effect is <20 ng/mL.

    Endotoxin level

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

  • Form

    Lyophilized

• Background

  • Background

    Interleukin 28A (IL-28A) predicts a molecular mass of 22.3 kDa. IL-28 comes in two isoforms, IL-28A and IL-28B, and plays a role in immune defense against viruses, including the induction of an antiviral state by turning on Mx proteins, 2',5'-oligoadenylate synthetase as well as ISGF3G.

    Synonyms

    IFN-lambda-2, Cytokine Zcyto20, Interleukin-28A, IL-28A

  • Uniprot ID

    #Q8IZJ0

    Sequence Note

    Pro27-Val200

• Instruction

  • Reconstitution

    It is recommended to reconstitute the lyophilized protein in sterile H₂O to a concentration not less than 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.
