IL4R ELISA kits are immunoassay tools for the measurement of the protein interleukin 4 receptor, which is encoded by the IL4R gene in humans. Functionally, this protein is a known receptor for both interleukin 4 and interleukin 13. The canonical protein structure is reported to have an amino acid length of 825 residues, a mass of 89.7 kDa, and is a member of the Type I cytokine receptor protein family. It is known to be localized in the cell membrane and is secreted. As many as 3 protein isoforms have been reported. The protein has been noted to be post-translationally glycosylated, cleaved and phosphorylated. Other alias names for this target include IL-4RA, IL4RA, interleukin-4 receptor subunit alpha, IL-4 receptor subunit alpha, interleukin 13 receptor, and CD124.
The detection range for different IL4R ELISA kits can vary, with some assays measuring target concentrations as low as 3.125 pg/mL and as high as 20 ng/mL. Click on the products below for more detailed ELISA kit information, such as target reactivity and assay sensitivity.
