| 蛋白构建 | A DNA sequence encoding the Human Interferon alpha 2 / IFNA2 (P01563-1) (Met1-Glu188) was expressed with a C-terminal polyhistidine tag followed by an AVI tag. The expressed protein was biotinylated in vivo by the Biotin-Protein ligase (BirA enzyme) which is co-expressed. | 
| 蛋白纯度 | ≥ 95% as determined by SDS-PAGE. ≥ 90% as determined by SEC-HPLC. | 
| 分子量 | 22.53 kDa (predicted); 25.1 kDa and 23.5 kDa (reducing contition, due to glycosylation) | 
| 内毒素 | < 1.0 EU per μg of the protein as determined by the LAL method | 
| 缓冲液 | Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hardcopy of datasheet or the lot-specific COA. | 
| 复溶方法 | Please refer to the lot-specific COA. | 
| 存储 | 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. | 
| 运输方式 | In general, Lyophilized powders are shipping with blue ice. | 
| 研究背景 | IFNA2 (Interferon Alpha 2) is a Protein Coding gene. This gene is a member of the alpha interferon gene cluster on chromosome 9. The encoded protein is a cytokine produced in response to viral infection. Type I Interferons (IFNs) are well-known cytokines that exert antiviral activity, antitumor activity, and immunomodulatory effects. Interferon tau (IFNT), a type I IFN similar to alpha IFNs (IFNA), is the pregnancy recognition signal produced by the ruminant conceptus. Among the IFN-α genes, a total of 28 different sequence variants have been described. The three principal subtypes of IFNα-2 are designated α-2a, α-2b, and α-2c. IFNα-2b is being the predominant allele while IFNα-2a is less predominant and IFNα-2c only a minor allelic variant. |
