IFN-omega is a type I interferon, which can be induced by virus-infected leukocytes. Members of the type I interferon family, which includes IFN-alpha, IFN-beta, and IFN-omega, signal through IFNAR-1/IFNAR-2 receptor complex, and exert antiviral and antiproliferative activities. IFN- omega exhibits about 75% sequence homology with IFN-alpha, and contains two conserved disulfide bonds, which are necessary for full biological activity. Recombinant Human IFN-omega is a 19.9 kDa protein consisting of 172 amino acid residues.
Human IFNW1 expressed in E.coli
CAT# CSC-CTK0197-100 (100 μg); CAT# CSC-CTK0197-500 (500 μg)
Greater than 98% as determined by SDS-PAGE and RP-HPLC analysis.
The ED50 was determined by a cytotoxicity assay using Human TF-1 cells is ≤ 0.01 ng/ml, corresponding to a specific activity of Greater than 1 x 10^8 units/mg.
Less than 1 EU/μg.
Sterile-filtered through a 0.2 micron filter. Lyophilized from a protein solution with no additives.
Please centrifuge product briefly before opening vial. The lyophilized protein should be reconstituted in sterile, ultrapure water or aqueous buffers to a concentration of 0.1- 1.0 mg mg/ml. This solution can then be diluted into other aqueous buffers and stored at -20°C for future use.
Storage & Stability
The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted protein should be used immediately or stored long-term in undiluted working aliquots at -20°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.
