• Cat.No.: Ifna1-40M
• Product Overview: Recombinant Mouse Ifna1 Protein (Cys24-Lys189) with N-His tag was expressed in E. coli and Animal-free as well as Carrier-free.

Specification

• Description: Interferon Alpha 1a (IFN alpha 1a) is a leukocyte interferon, which is a variant of Interferon-alpha. IFN-alpha 1a is a 18.4 kDa protein containing 166 amino acid residues. It could bind the interferon receptors that activates the signal transduction of immune responses through the Jak/STAT pathway in leukocytes and lymphoblastoid cells.
• Source: E. coli
• Species: Mouse
• Tag: N-His
• Form: Lyophilized
• Bio-activity: Measure by its ability to protect L929 cells infected with encephalomyocarditis (EMC) virus. The ED50 for this effect is < 10 pg/mL. The specific activity of recombinant mouse IFN alpha 1a is > 4 × 10⁷ IU/mg.
• Molecular Mass: The protein has a calculated MW of 19.93 kDa.
  The protein migrates as 17-25 kDa under reducing condition (SDS-PAGE analysis).
• Protein Length: Cys24-Lys189
• 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.
