Active Recombinant Human IL28B Protein (Val22-Val196), C-His tagged, Animal-free, Carrier-free

• Cat.No.: IL28B-130H
• Product Overview: Recombinant Human IL28B Protein (Val22-Val196) with C-His tag was expressed in E. coli and Animal-free as well as Carrier-free.

Specification

• Description: Interleukin-28B (IL-28B, now known as Interferon Lambda 3, IFN-λ3) is a 19.77 kDa member of type III IFN family with 176 amino acid residues. IL-28B is expressed by epithelial tissues. Cytokine with antiviral, antitumor and immunomodulatory activities. Able to activate JAK/STAT signaling pathway via binding its receptor IFNLR1 in epithelial cells.
• Source: E. coli
• Species: Human
• Tag: C-His
• Form: Lyophilized
• Bio-activity: Measure by its ability to protect HepG2 cells infected with encephalomyocarditis (EMC) virus. The ED50 for this effect is < 5 ng/mL.
• Molecular Mass: The protein has a calculated MW of 25.57 kDa.
  The protein migrates as 21 kDa under reducing condition (SDS-PAGE analysis).
• Protein Length: Val22-Val196
• Endotoxin: < 0.01 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 8.0.
• 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.
