Detection of human IL-22 using HTRF (an alternative to ELISA) Cisbio kit 62HIL22PEG.
Interleukin 22 is a type 2 cytokine (member of the IL10 family) and plays an essential role in innate protective immunity against extracellular pathogens. It induces pro-inflammatory responses, allows production of antimicrobial peptides. IL-22 is also involved in wound-healing and regeneration of epithelial cells. Human IL-22 is produced on inflammation site by Th17 CD4+ cells, activated T-cells, Th1 and NK cells. After being secreted, it targets non-hematopoietic cells and binds to IL22R that is restricted to tissue-resident cells (fibroblasts, epithelial cells). Downstream signaling involves phosphorylation of Jak1 and Tyk2 and subsequent activation of STAT3. Cisbio’s Human IL22 kit is a homogeneous, add and read assay to measure IL-22 secretion in cell supernatants. It offers a fast, efficient alternative to ELISA.
This data analysis tool performs quantitative analysis of samples using a 1/y² weighted Four Parameter Logistic (4PL) curve fit. Provide your ratio calculated measurement data (665nm/620nm). Calculations are performed as follows:
1. Delta Ratio is computed for each sample using the zero standard (Zero).
2. The standard data points (Concentration vs. Delta Ratio) are plotted and the curve is fitted through the points. The concentrations of the samples are determined from the fit with any specified dilution factors applied.
3. The %CV and Standard Deviation are calculated for each replicated sample.
If the entire plate was read then supply the measured value for each well. Alternatively, if only specific parts of the plate were read then list only those measured values. In this case an additional step is required: under the Microplate section below, select or create a layout which defines which wells were read and which were not. More...
