Mouse IL4R ELISA Kit (ab256403) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of IL4R protein in cell culture supernatant, cit plasma, edta plasma, hep plasma, and serum. It uses our proprietary SimpleStep ELISA® technology. Quantitate Mouse IL4R with 7.08 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.
IL4R is a receptor for both interleukin 4 and interleukin 13. IL-4R is involved in the JAK1/2/3-STAT6 pathway. The IL4 response is essential in promoting Th2 differentiation and regulating IgE production, chemokine and mucus production at sites of allergic inflammation. In certain cell types, IL-4R can signal through activation of insulin receptor substrates, IRS1/IRS2. Soluble IL4R (sIL4R) inhibits IL4-mediated cell proliferation and IL5 upregulation by T-cells. Mouse IL-4R shares 52.2%, 76.0%, 50.7%, and 52.4% sequence homology with human, rat, bovine, and monkey respectively.

FunctionReceptor for both interleukin 4 and interleukin 13. Couples to the JAK1/2/3-STAT6 pathway. The IL4 response is involved in promoting Th2 differentiation. The IL4/IL13 responses are involved in regulating IgE production and, chemokine and mucus production at sites of allergic inflammmation. In certain cell types, can signal through activation of insulin receptor substrates, IRS1/IRS2.
Soluble IL4R (sIL4R) inhibits IL4-mediated cell proliferation and IL5 up-regulation by T-cells.
Tissue specificityIsoform 1 and isoform 2 are highly expressed in activated T-cells.
Sequence similaritiesBelongs to the type I cytokine receptor family. Type 4 subfamily.
Contains 1 fibronectin type-III domain.
DomainThe extracellular domain represents the IL4 binding protein (IL4BP).
The WSXWS motif appears to be necessary for proper protein folding and thereby efficient intracellular transport and cell-surface receptor binding.
The box 1 motif is required for JAK interaction and/or activation.
Contains 1 copy of a cytoplasmic motif that is referred to as the immunoreceptor tyrosine-based inhibitor motif (ITIM). This motif is involved in modulation of cellular responses. The phosphorylated ITIM motif can bind the SH2 domain of several SH2-containing phosphatases.
modificationsOn IL4 binding, phosphorylated on C-terminal tyrosine residues. Phosphorylation on any one of tyrosine residues, Tyr-575, Tyr-603 or Tyr-631, is required for STAT6-induced gene induction.
The soluble form (sIL4R/IL4BP) can also be produced by proteolytic cleavage at the cell surface (shedding) by a metalloproteinase.
Cellular localizationSecreted and Cell membrane.

SimpleStep ELISA technology allows the formation of the antibody-antigen complex in one single step, reducing assay time to 90 minutes. Add samples or standards and antibody mix to wells all at once, incubate, wash, and add your final substrate. See protocol for a detailed step-by-step guide.
The IL4R standard curve was prepared as described in Section 10. Raw data values are shown in the table. Background-subtracted data values (mean +/- SD) are graphed.
The concentrations of IL4R were measured in duplicates, interpolated from the IL4R standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 10%, plasma (citrate) 10%, plasma (EDTA) 10%, and plasma (heparin) 5%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean IL4R concentration was determined to be 14.42 ng/mL in serum, 9.87 ng/mL in plasma (citrate), 10.28 ng/mL in plasma (EDTA), 12.14 ng/mL in plasma (heparin).
The concentrations of IL4R were measured in duplicates, interpolated from the IL4R standard curves and corrected for sample dilution. Undiluted samples are as follows: spleen tissue culture supernatant 50%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean IL4R concentration was determined to be 1465.50 pg/mL in spleen tissue culture supernatant.
