IFN-ω is a member of the type I interferon family, that can be induced by virus infected leukocytes and exert antiviral and anti-proliferative activities. IFN-ω shares about 75% sequence homology with IFN-α. There are two conserved disulfide bonds that are necessary for full biological activity.

<0.1 EU per 1 μg of the protein by the LAL method.
Measure by its ability to induce cytotoxicity in TF-1 cells. The ED50 for this effect is <0.02 ng/mL. The specific activity of recombinant human IFN omega is approximately >5 x107 IU/mg.
>95% as determined by SDS-PAGE. Ni-NTA chromatography
The protein was lyophilized from a solution containing 1X PBS, pH 7.4.
It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 100 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
Lyophilized protein should be stored at -20°C. Upon reconstitution, protein aliquots should be stored at -20°C or -80°C.
Please use within one month after protein reconstitution.
