| 항목 | 내용 |
|---|---|
| Product name | Recombinant Human IFN alpha2a |
| Description | Recombinant Human Interferon Alpha-2a is produced by our E.coli expression system and the target gene encoding Cys24-Glu188 is expressed. |
| Expression Host | E.coli |
| Accession | P01563 |
| Molecular weight | 19.24 KDa |
| Apparent molecular weight | 16 KDa (reducing conditions) |
| Other names | Interferon Alpha-2; IFN-Alpha-2; Interferon Alpha-A; LeIF A; IFNA2 |
| Formulation | Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.2. |
| Purity | Greater than 95% as determined by reducing SDS-PAGE. |
| Endotoxin | Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test. |
| Redissolve | Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. |
| Storage | Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months. |
| Delivery condition | The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature listed below. |
Background
At least 23 different variants of IFN-α are known. The individual proteins have molecular masses between 19–26 kDa and consist of proteins with lengths of 156–166 and 172 amino acids. All IFN-α subtypes possess a common conserved sequence region between amino acid positions 115–151 while the amino-terminal ends are variable. Many IFN-α subtypes only differ in their sequences by one or two positions. Naturally occurring variants also include proteins truncated by 10 amino acids at the carboxy-terminal end.
