IL22RA2 ELISA Kit (Rat)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Interleukin 22 Receptor Alpha 2 (IL22Ra2) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Interleukin 22 Receptor Alpha 2 (IL22Ra2) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

Crf2-s1; cytokine receptor family II soluble 1; cytokine receptor family type 2, soluble 1; IL-22 receptor subunit alpha-2; IL22BP; IL-22BP; IL-22RA2; IL-22R-alpha-2; interleukin 22 receptor, alpha 2; interleukin-22 receptor subunit alpha-2; interleukin-22-binding protein.

Receptor for IL22. Binds to IL22, prevents interaction with the functional IL-22R complex and blocks the activity of IL22 (in vitro) . May play an important role as an IL22 antagonist in the regulation of inflammatory responses.

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Interleukin 22 Receptor Alpha 2 (IL22Ra2) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Interleukin 22 Receptor Alpha 2 (IL22Ra2) . Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Interleukin 22 Receptor Alpha 2 (IL22Ra2), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of Interleukin 22 Receptor Alpha 2 (IL22Ra2) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
