  • Recommended Products
  • Cat.No.
  • CSC-CTK0197
  • Description
  • 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.

  • Activity
  • 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.
  • Endotoxin Level
  • Less than 1 EU/μg.
  • Formulation
  • Sterile-filtered through a 0.2 micron filter. Lyophilized from a protein solution with no additives.
  • Reconstitution
  • 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.
