Technical Data


Recombinant protein


IFN-ω is a type I interferon that can be induced by virus-infected leukocytes. Members of the type I interferon family, which includes IFN-α, IFN-β, and IFN-ω, signal through the IFNAR-1/IFNAR-2 receptor complex, and exert antiviral and antiproliferative activities. IFN-ω exhibits about 75% sequence homology with IFN-α, and contains two conserved disulfide bonds that are necessary for full biological activity. Recombinant Human IFN-ω is a 19.9 kDa protein consisting of 172 amino acid residues.

Biological Activity

The ED50 was determined by a cytotoxicity assay using Human TF-1 cells is 0.01 ng/ml, corresponding to a specific activity of 1×108 units/mg.


Endotoxin level is <0.1 ng/μg of protein (<1EU/μg).


Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 1.0 mg/ml. Do not vortex. This solution can be stored at 2–8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at –20°C to –80°C.

Cytokines and chemokines and related molecules


IFNω belongs to class I interferon. In the human genome, the IFNω gene family consists of seven members located on chromosome 9. IFNω is a major component of human leukocyte IFN. Therapeutically administered IFNω may cause measurable serum concentrations in the corresponding patients. Monitoring of these IFNω serum levels provides an important tool in therapy.
