Appearance Lyophilized powder. Formulation Lyophilized after extensive dialysis against PBS. Endotoxin Level <0.2 EU/μg, determined by LAL method. Reconstitution Reconstitute the lyophilized recombinant Human Interleukin-22 (rHuIL-22) to 100 μg/mL using ddH2O or PBS. Storage & Stability Lyophilized recombinant Human Interleukin-22 (rHuIL-22) 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 Interleukin-22 (IL-10-related T cell-derived inducible factor/IL-TIF/IL-22) is a novel cytokine belonging to the IL-10 family. Recombinant humanIL-22 (hIL-22) is found to activate the signal transducers and activators of transcription factors 1 and 3 as well as acute phase reactants in several hepatoma cell lines, suggesting its involvement in the inflammatory response. IL-22 is a member of interleukin-10 family of cytokines, which also includes IL-19, IL-20, and IL-24 in addition to IL-10 and a number of its viral homologs[1]. |
