IFN alpha 2b Human

Cat.-Nr.: CS-C1054

Description

IFN-α 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 IFNα2A and IFNα2B is in the amino acid present at position 23. IFN-α 2a has a lysine at that position 23 while IFN-α 2b has arginine.

The IFN-α 2b gene was obtained from human leukocytes.

The IFN-a 2b is purified by proprietary chromatographic techniques.

  • Solubility:It is recommended to reconstitute the lyophilized IFN-α 2b in sterile 18MΩ-cm H2O not less than 100µg/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 α 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.
