Description

Interferon-alpha 2b (IFNalpha 2b) is a Type I interferon made by leukocytes during viral infection. It has anti-viral and non-proliferative activity induced by JAK1-STAT signaling. IFN-alphas are the most widely used type for therapeutic purposes. IFN alpha 2b is a variant of IFN alpha 2a that differs by one amino acid. Human IFNa-2b is produced in E. coli. Recombinant human IFN alpha 2b is a non-glycosylated protein, containing 166 amino acids, with a molecular weight of 19.4 kDa.

Source

E. coli. Endotoxin level as measured by LAL is <0.05ng/ug or <0.5EU/ug.

Purity

Purity > 95% as determined by RP-HPLC and reducing and non-reducing SDS-PAGE. Protein Content determined by UV spectroscopy at 280 nm and analysis by RP-HPLC calibrated against a known standard. Quantitation on SDS-PAGE against a known standard.

Application Notes

The activity can be determined by the ability to induce antiviral activity. There is no biological assay data available at this time.

Storage

Store at -20C. Product is guaranteed one year from the date of shipment. Following reconstitution, store at -20C. We recommend to add a carrier protein (0.1% HSA or BSA) for long term storage.
