Description
Product Name: | Human IFN a 2b Recombinant Protein |
Product Code: | RPPB0384 |
Size: | 100µg |
Species: | Human |
Target: | IFN a 2b |
Synonyms: | IFN alpha 2b, IFNA, INFA2, MGC125764, MGC125765. |
Source: | Escherichia Coli |
Physical Appearance: | Sterile Filtered White lyophilized (freeze-dried) powder. |
Formulation: | Lyophilized from a (1 mg/ml) solution in containing 2.3 mg Sodium phosphate dibasic and 0.55 mg sodium phosphate monobasic buffer. |
Solubility: | It is recommended to reconstitute the lyophilized IFN-alpha 2b in sterile 18M?-cm H2O not less than 100�g/ml, which can then be further diluted to other aqueous solutions. |
Stability: | Lyophilized IFN although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IFN alpha 2b 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. |
Purity: | Greater than 98.0% as determined by(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. |

IFN-alpha is produced by macrophages and has antiviral activities. IFN stimulates the production of two enzymes: protein kinase and an oligoadenylate synthetase.
IFN-a 2b Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 166 amino acids and having a molecular mass of 19400 Dalton. The difference between IFNA2A and IFNA2B is in the amino acid present at position 23. IFN-alpha 2a has a lysine at that position 23 while IFN-alpha 2b has arginine.The IFN-alpha 2b gene was obtained from human leukocytes.The IFN-a 2b is purified by proprietary chromatographic techniques.
