    Expression System

    Escherichia coli

  • Affinity Tag

    His Tag (N-term)

    Storage 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 8.43 kDa.
    The protein migrates as 11 kDa under reducing condition (SDS-PAGE analysis).

  • Activity

    Measure by its ability to chemoattract BaF3 cells transfected with human CXCR2. The ED₅₀ for this effect is <0.5 ng/mL.

    Endotoxin Level

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

  • Form

    Lyophilized

• Background

  • Background

    C-X-C motif chemokine 7 (CXCL7) also named Pro-Platelet basic protein (PPBP), which is a chemokine of the intercrine alpha family. CXCL7is a 7.7 kDa protein containing 70 amino acid residues. CXCL7 is expressed by the platelets, which are activated. During vascular injury, CXCL7 controls the glucose metabolism, mitogenesis and neutrophil recruitment by the interaction with CXCR2.

• 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.
