Appearance Lyophilized powder. Formulation Lyophilized after extensive dialysis against PBS, pH 7.4. Endotoxin Level <1 EU/μg, determined by LAL method. Reconstitution Reconstitute the lyophilized recombinant Human Interferon Omega (rHuIFN-ω) to 0.1-1.0 mg/mL using sterile distilled water or aqueous buffer containing 0.1% BSA. Storage & Stability Lyophilized recombinant Human Interferon Omega (rHuIFN-ω) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping Room temperature in continental US; may vary elsewhere. Background Interferon-omega (IFN-omega), a type I interferon, is a monomeric glycoprotein distantly related in structure to IFN-alpha and IFN-beta, but unrelated to IFN-gamma. The human type I interferon receptor complex, which mediates the biological activity of IFN-alpha and IFN-beta, also binds IFN-omega. IFN-omega is secreted by virus-infected leukocytes. Human IFN-ω binds to the α/β receptor but not to the interferon γ receptor[1]. IFN-omega has antiviral function on hepatitis B virus replication in human hepatoma cells[2]. IFN-ω also has been explored as a treatment option for some diseases or viral infections in humans and other animals[3]. |
