• Cat.No.: Il13-49M
• Product Overview: Recombinant Mouse Il13 Protein (Pro22-Fhe131) with C-His tag was expressed in E. coli and Animal-free as well as Carrier-free.

Specification

• Description: Interleukin 13 (IL-13) with a molecular mass of 10 kDa cytokine, it secreted by T helper type 2 (Th2) cells, CD4 cells, natural killer T cell, mast cells, basophils, eosinophils and nuocytes. It is homologous to IL-4 and shares many of its biologic activities on mononuclear phagocytic cells, endothelial cells, epithelial cells, and B cells.
• 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 < 4 ng/mL. The specific activity of recombinant mouse IL-13 is > 2.5 × 10⁵ IU/mg.
• Molecular Mass: The protein has a calculated MW of 13.06 kDa.
  The protein migrates about 11 kDa under reducing condition (SDS-PAGE analysis).
• Protein Length: Pro22-Fhe131
• Endotoxin: < 0.1 EU/μg of the protein by the LAL method.
• Purity: >95% 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 2 weeks 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.
