Human IFN a 2a Protein

• Catalog Number: orb80386
• Category: Proteins
• Description: Recombinant of Human IFN a 2a protein
• Form/Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
• Purity: Greater than 99.0% as determined by both:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
• Solubility (25°C): 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.
• Protein 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
• Source: Nicotiana Sp.Plant
• Biological 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 × 108 Units/mg in reference to a viral resistance assay using bovine kidney MDBK cells.
• Storage: Stability: Lyophilized Interferon alpha 2a although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IFN-alpha 2a should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles
• Buffer/Preservatives: Lyophilized, containing 50% SDS.
• Alternative names: Leukocyte interferon, B cell interferon, Type I in
• Note: For research use only
• Application notes: Cytokines And Growth Factors
• Expiration Date: 6 months from date of receipt.
