SYNONYMS
IFN alpha 2b, IFNA, INFA2, MGC125764, MGC125765.
INTRODUCTION
IFN-alpha is produced by macrophages and has antiviral activities. IFN stimulates the production of two enzymes: protein kinase and an oligoadenylate synthetase.
DESCRIPTION
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.

FORMULATION
SOLUBILITY
It is recommended to reconstitute the lyophilized IFN-alpha 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 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
(b) Analysis by SDS-PAGE.

BIOLOGICAL ACTIVITY
PROTEIN CONTENT
1. UV spectroscopy at 280 nm using the absorbency value of 0.924 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).
2. Analysis by RP-HPLC, using a calibrated solution of IFN alpha 2b as a Reference Standard.
