The ProQuantum Mouse IL-22 Immunoassay Kit is designed to provide quantitative measurements of mouse IL-22 in small sample volumes. Utilizing proximity-based amplification technology, the assay combines the analyte specificity of high-affinity antibody-antigen binding with the signal detection and amplification capabilities of real-time PCR to achieve a simple yet powerful next-generation protein quantitation platform. A user-friendly workflow combined with intuitive software for analytics enables sample-to-answer in just 2 hours.
• High sensitivity-detect low levels of protein with greater sensitivity than traditional methods
• Broad dynamic range-5 logarithmic units, minimizing sample dilutions to ensure they fall within the range
• Small sample consumption-use 2-5 µL of sample (compared to 75 µL for triplicate wells with other methods)
• Fast, easy workflow-2 hours from sample to answer, with no wash steps
• No proprietary instrument to purchase-runs on any real-time PCR instrument
ProQuantum immunoassays utilize a matched pair of target-specific antibodies, each conjugated to a DNA oligonucleotide. During antibody-analyte binding, the two DNA oligos are brought into close proximity, which allows for ligation of the two strands and subsequent creation of a template strand for amplification. This platform leverages the sensitivity and large dynamic range of Applied Biosystems TaqMan real-time PCR technology (Figure 1).
The assay workflow is fast and easy-2 steps in 2 hours. There are a total of 7 components in each kit (Figure 2). First, mix the antibody-conjugates, dilute the sample, and create the standard curve in a working plate. Then, using a multi-channel pipette, add the antibody-conjugates and sample (or standard) into the wells of a PCR plate and incubate for 1 hour. Combine the master mix and ligase and add to the wells of the PCR plate, then run the plate on any qPCR instrument. After the run is complete, import the results file into the ProQuantum software (cloud-based version at https://apps.thermofisher.com/apps/proquantum). Using this software, the data can be analyzed easily to obtain protein concentration values. The software allows you to set up standard curves, design plate layouts, apply a 5PL weighted algorithm, and obtain robust statistical group-wise comparisons.
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.
