Product Introduction
Bioactivity
Chemical Properties
Storage & Solubility Information
| Bioactivity | Measured in antiviral assays using WISH human amnion cells infected with vesicular stomatitis virus(VSV). The ED50 for this effect is typically 2-8 pg/mL.  |
| Description | Interferon alpha 4/IFNA4 Protein, Human, Recombinant (His) is expressed in Baculovirus insect cells with His tag. The predicted molecular weight is 20.7 kDa and the accession number is P05014. |
| Species | Human |
| Expression System | Baculovirus Insect Cells |
| Tag | C-His |
| Accession Number | P05014 |
| Construction | A DNA sequence encoding the human IFNα 4a (NP_066546.1)) (Met 1-Asp 189) was fused with a polyhistidine tag at the C-terminus. Predicted N terminal: Cys 24 |
| Protein Purity | > 88 % as determined by SDS-PAGE  |
| Endotoxin | < 1.0 EU/μg of the protein as determined by the LAL method. |
| Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing 20 mM Tris, 500 mM NaCl, pH 7.4, 10% gly. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization. |
| Reconstitution | Reconstituted with sterile deionized water to 0.25 mg/mL. Reconstitution conditions may vary depending on the lot. |
| Stability & Storage | It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
| Shipping | In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice. |
| Synonyms | MGC142200, interferon, α4, interferon, alpha 4, INFA4, IFN-α4a, IFN-alpha4a |
| Research Background |
| Molecular Weight | 20.7 kDa (predicted); 20 kDa (reducing conditions) |
| Storage | Lyophilized powder: -20~-80°C for 1 year | Solution: -80°C for 6 months |
