Reconstitution Dissolved in sterile water, it is recommended to add 0.1% HSA or BSA for long-term preservation. STORAGE Stability and Storage 12 months from date of receipt at -20°C to -70°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for almost 6 months (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage. BACKGROUND IL-22 is a relatively new cytokine that is characterized by several unique biological properties. IL-22 is a secreted cytokine produced mainly by cells of the lymphoid lineage and innate lymphoid cells. IL22 is a member of a group of cytokines called the IL-1 family of IL-1 superfamily a class of potent mediators of cellular inflammatory responses. IL22 has been shown to be an essential mediator in epithelial regeneration and wound repair. IL22 along with IL-17 is rapidly produced by splenic LTi-like cells and can be also produced by Th17 cells and likely plays a role in the coordinated response of both adaptive and innate immune systems.IL22 biological activity is initiated by binding to a cell-surface complex composed of IL-22R1 and IL-1R2 receptor chains and further regulated by interactions with a soluble binding protein, IL-22BP, which shares sequence similarity with an extracellular region of IL-22R1. IL22 also plays an important role in controlling the risk of inflammation-induced preterm birth. Data SDS-PAGE Bioactivity Active Recombinant Mouse IL-22 Protein was determined by SDS-PAGE with Coomassie Blue, showing a band at 22-35 kDa. Fully biologically active determined by the dose dependent induction of IL-10 secretion in COLO-205 cells. ED50 is 5-10 ng/mL. For Research Use Only! Ver. No.: V 1.0-202102 仅供科研用途，不可用于临床诊断！
