Interferon omega-1, Interferon alpha-II-1, IFNW1.

IFN-Omega 1 is a type I interferon, that can be induced by virus-infected leukocytes. Type I interferon family members, which include IFN-alpha, IFN-beta, and IFN-omega, signal through IFNAR-1/IFNAR-2 receptor complex, and wield antiviral and antiproliferative activities. IFNW1 exhibits about 75% sequence homology with IFN-a, and contains 2 conserved disulfide bonds, which are essential for full biological activity.

Interferon-Omega 1 Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 172 amino acids and having a molecular mass of 19.9kDa.
The Interferon-Omega 1 is purified by proprietary chromatographic techniques.

Lyophilized from a 0.2µm filtered concentrated solution in PBS, pH 7.4.

It is recommended to reconstitute the lyophilized IFNW1 in sterile 18M?-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

Lyophilized IFNW1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IFNW1 should be stored at 4°C between 2-7 days and for future use below -18°C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
