Appearance Lyophilized powder. Formulation Lyophilized after extensive dialysis against PBS. Endotoxin Level <1 EU/μg, determined by LAL method. Reconstitution Reconstitute the lyophilized recombinant Human Interferon-gamma (rHuIFN-γ) to 100 μg/mL using ddH2O or diluted with PBS. Storage & Stability Lyophilized recombinant Human Interferon-gamma (rHuIFN-γ) 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 Human Interferon-gamma (hIFNγ) is naturally produced by CD4+ T helper cell type 1 (Th1) lymphocytes, CD8+ cytotoxic lymphocytes, natural killer (NK) cells, B cells, NKT cells, and professional antigen-presenting cells (APCs). Secretion of hIFNγ by NK cells and APCs is important in early host reactions against infection while production of hIFNγ by T lymphocytes is important in the adaptive immune response. hIFNγ shows antiviral and antitumor activity and is involved in complex interactions of cellular metabolism and differentiation[1]. Interferon-gamma (IFN-γ) is a cytokine with potent immunomodulatory propertiy. IFN-γ activates cells via a different receptor than IFN-α and IFN-β, which accounts for the different physiological properties of the proteins[2]. |
