Active Recombinant Human IFNA2 Protein, His-tagged

• Cat.No.: IFNA2-1555H
• Product Overview: Recombinant Human IFNA2 fused with His tag at the C-terminus was produced in Nicotiana Sp.Plant.

Specification

• Species: Human
• Source: Nicotiana Sp.
• Tag: His
• Description: IFN-alpha is produced by macrophages and has antiviral activities. Interferon stimulates the production of two enzymes: protein kinase and an oligoadenylate synthetase.
• Form: Lyophilized, containing 50% SDS.
• Bio-activity: The specific activity was determined by a quantitative gene report bioassay using human Type I interferon-sensitive cells. Compared with bacterial derived recombinant IFN-a 2a, assayed in the same conditions, plant derived IFN-alpha 2a showed 6.1 × 10^8 Units/mg in reference to a viral resistance assay using bovine kidney MDBK cells.
• Molecular Mass: Interferon Alpha Human 2a Recombinant produced in Plant is a single, glycosylated, polypeptide chain containing 165 amino acids and having a molecular mass of 19 kDa.
• AA sequence: The sequence of the first twelve N-terminal amino acids was determined and was found to be Cys-Asp-Leu-Pro-Gln-Thr-His-Ser-Leu-Gly-Ser-Arg.
• Purity: Greater than 99.0% as determined by both:
  (a) Analysis by RP-HPLC.
  (b) Analysis by SDS-PAGE.
• Storage: Lyophilized Interferon alpha 2a although stable at room temperature for 3 weeks, should be stored desiccated below -18 centigrade. Upon reconstitution IFN-alpha 2a should be stored at 4 centigrade between 2-7 days and for future use below -18 centigrade.
  For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
  Please prevent freeze-thaw cycles.
• Reconstitution: It is recommended to reconstitute the lyophilized Interferon-alpha 2a in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
