Interleukin-4 receptor subunit alpha (IL-4RA)
Links to databases
This is a transmembrane receptor for both interleukin 4 and interleukin 13, which regulate IgE production and, chemokine and mucus production at sites of allergic inflammation. The binding of IL-4 or IL-13 to the IL-4 receptor on the surface of macrophages results in an alternative activation, which downregulate inflammatory mediators such as IFN? during immune responses.
Analytical Measuring Range
Please note: the technical data reported below refers to the measured value in the in vitro validation assays. The calibrator curve below shows the performance of the assay with the estimated sensitivity and dynamic range parameters indicated. These curves are generated during the assay validation process using recombinant antigens. Please note that when analyzing biological samples the data generated will be given in the form of relative quantification (NPX values) and cannot be converted to absolute protein concentrations. For more info about NPX measurements, please visit our FAQ page (https://www.olink.com/question/what-is-npx).
Calibrator curve for validation data (generated in multiplex)
- Within run precision Coefficient of Variation (CV)
- Between run precision Coefficient of Variation (CV)
Precision (repeatability) is calculated from linearized NPX values over LOD.
