Reconstitution Reconstitute the lyophilized recombinant Murine Interleukin-22 (rMuIL-22) to 100 μg/mL using ddH2O or PBS. Storage & Stability Lyophilized recombinant Murine Interleukin-22 (rMuIL-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-22) is a member of the IL-10 family of cytokines, expressed predominantly by subsets of innate lymphoid cells (ILCs) and activated T cells, including T helper 1 (TH1) cells, TH17 cells and TH22 cells. IL-22 can be recognized by a heterodimeric receptor complex that consists of two transmembrane subunits: IL-22R1 and IL-10R2. The binding of IL-22 to its receptor activates the JAK/STAT and MAPK signaling pathway, resulting in gene expression or repression. Since the IL-10R2 is shared by five cytokines (IL-10, IL-22, IL-26, IL-28, and IL-29) and is widely expressed in most cells, the expression of the IL-22R1 determines whether a cell is the target of IL-22. IL-22 has a considerable therapeutic potential in graft-versus-host disease (GVHD), which is a frequent and challenging complication following allogeneic stem cell transplantation[1]. |
