Description of Human IFN-omega

Recombinant Human IFN-Omega 1 produced in E. coli is a 19.9kDa single, non-glycosylated, polypeptide chain containing 172 amino acids. The IFN-Omega 1 is purified by proprietary chromatographic techniques.

Biological Activity

The ED₅₀ of ≤ 0.01 ng/ml was determined by a cytotoxicity assay using Human TF-1 cells. It corresponds to a specific activity of ≥ 1.0 x 10⁸ units/mg.

Reconstitution

We recommend a quick spin followed by reconstitution in water to a concentration at least 100µg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week or in working aliquots at -20°C to -80°C. Working aliquots should be at the highest practical concentration. For long term storage we recommend to add at least 0.1% HSA (order number: 2835.955.xyz or 2835.958.xyz) or BSA (order number: 2835.919.xyz).

Stability

Lyophilized Human IFN-omega although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Human IFN-omega should be stored at 4°C between 2-7 days and for future use below -18°C. Please avoid repeated freeze-thaw cycles.
