• Cat.No.: Il5-60M
• Product Overview: Recombinant Mouse Il5 Protein (Met21-Gly133) with C-His tag was expressed in E. coli and Animal-free as well as Carrier-free.

Specification

• Description: 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).
• Source: E. coli
• Species: Mouse
• Tag: C-His
• Form: Lyophilized
• Bio-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 × 10⁶ IU/mg.
• Molecular Mass: The protein has a calculated MW of 13.93 kDa.
  The protein migrates as 11-17 kDa under reducing condition (SDS-PAGE analysis).
• Protein Length: Met21-Gly133
• Endotoxin: < 0.1 EU/μg of the protein by the LAL method.
• Purity: >98% as determined by SDS-PAGE analysis.
• Storage: This product is stable after storage at:
  -20 centigrade for 12 months in lyophilized state from date of receipt.
  -20 or -80 centigrade for 1 month under sterile conditions after reconstitution.
  Avoid repeated freeze/thaw cycles.
• Storage Buffer: Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.
• 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 centigrade or lower for long term storage.
