• Preparation: Produced from sera of rabbits immunized with highly pure Recombinant Human IL-22
• Anti-Human IL-22-specific antibody was purified by affinity chromatography and then biotinylated
• Sandwich ELISA: To detect Human IL-22 by sandwich ELISA (using 100 μL/well) a concentration of 0.25-1.0 μg/mL of this antibody is required
• This biotinylated polyclonal antibody, in conjunction with PeproTech Polyclonal Anti-Human 4-1BBL (500-P211) as a capture antibody, allows the detection of at least 0.2-0.4 ng/well of Recombinant Human IL-22
• Western Blot: To detect Human IL-22 by Western Blot analysis this antibody can be used at a concentration of 0.1-0.2 μg/mL
• Used in conjunction with compatible development reagents the detection limit for Recombinant Human IL-22 is 1.5-3.0 ng/lane, under either reducing or non-reducing conditions
• 500-P211BT-1MG will be provided as 2 x 500 μg IL-22 also known as IL-10-related T-cell derived inducible factor, is an alpha helical cytokine and is considered a member of the IFN-IL-10 family, which includes IL-19, IL-20, IL-24, IL-26, IL-28, IL-29, and the type I and II interferons
• IL-22 is produced mainly by activated T cells and NK cells
• In humans, the IL-22 gene is located on the q arm of chromosome 12, and is structurally related to IL10
• IL-22 acts by engaging the heterodimeric receptor complex consisting of primary receptor IL-22R1 and accessory receptor IL-10R2
• IL-22R1 also binds IL-20 and IL-24; IL-10R2 also binds IL-10, IL-27, IL-28, and IL-29
• Binding of IL-22 to its receptor complex induces signal transduction, particularly via the JAK-STAT pathway
• In addition to the membrane-bound IL-22R1/IL-10R2 complex, a soluble single-chain IL-22 receptor termed IL-22BP has been found to antagonize IL-22 binding and signaling
• IL-22 appears not to directly influence immune cells, and major targets of the cytokine appear to be nonimmune cells, such as cells of the skin, digestive and respiratory system, as well as hepatocytes, and keratinocytes
• IL-22 has been described as an effector cytokine of the Th17 lineage
• Along with IL-17A and IL-17F, IL-22 regulates genes associated with innate immunity of the skin
• IL-17A, IL-17F and IL-22 are all co-expressed by Th17 cells, however, they are differentially regulated
• The effects of IL-22 include induction of acute phase reactants and antimicrobial proteins, as well as increasing the mobility of keratinocytes
• IL-22 is highly expressed during chronic inflammation, and found to activate intracellular kinases and transcription factors
• IL-22 is critical for host defense against infections of extracellular pathogens, and promotes wound-healing responses
• IL-22 is upregulated in activated T cells
• IL-22 has been reported to mediate IL-23-induced acanthosis and dermal inflammation through activation of STAT3.
