    Mouse

    Expression system

    Escherichia coli

  • Affinity Tag

    His Tag (C-term)

    Buffer

    Lyophilized from a 0.2 µm filtered solution of PBS, pH 7.4.

  • Purity

    >98% as determined by SDS-PAGE analysis.

    Molecular weight

    The protein has a calculated MW of 13.93 kDa.
    The protein migrates as 11-17 kDa under reducing condition (SDS-PAGE analysis).

  • Activity

    Measure by its ability to induce TF-1 cells proliferation. The ED₅₀ for this effect is <0.2 ng/mL. The specific activity of recombinant mouse IL-5 is > 5 x 10⁶ IU/mg.

    Endotoxin level

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

  • Form

    Lyophilized

• Background

  • Background

    Interleukin 5 (IL-5) is a 45-60 kDa homodimeric cytokine that functions principally in the eosinophil arm of the Th2 response. It is a member of the helical bundle family of cytokines, along with IL-3, IL-4, and granulocyte macrophage-colony stimulating factor (GM-CSF).

• 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.
