Predicted MW	The protein has a calculated MW of 20.93 kDa. The protein migrates as 20 kDa under reducing condition (SDS-PAGE analysis).
Purity	>95% as determined by SDS-PAGE.
Buffer	The protein was lyophilized from a 0.2 µm filtered solution containing 1X PBS, pH 7.4.
Applications	Cell culture
Storage	Lyophilized protein should be stored at -20°C for 1 year. Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months. Avoid repeated freeze/thaw cycles.
Bioactivity	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.
Endotoxin	<0.1 EU per 1 μg of the protein by the LAL method.
Reference Data
