Product overview
Mouse IL-6 R alpha ELISA Kit (ab203360) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of IL-6 R alpha protein in cell culture supernatant, serum, urine, and plasma. It uses our proprietary SimpleStep ELISA® technology. Quantitate Mouse IL-6 R alpha with 12.6 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 stripsA 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

Notes
Interleukin-6 Receptor (IL-6R, IL-6 Receptor), also known as Interleukin-6 Receptor subunit alpha and membrane glycoprotein 80, is part of a receptor that binds Interleukin-6 (IL-6). IL-6 Receptor weakly binds IL-6 with a low affinity, and then is presented to gp130 to facilitate transition into a high affinity signaling competent hexamer. Activation may lead to regulation of the immune response, acute-phase reactions and hematopoiesis. The production of IL-6 Receptor has been implicated in the pathogenesis of many diseases, including multiple myeloma, auto immune diseases and prostate cancer.IL-6 Receptor has two isoforms. The first is a transmembrane protein in which the N-terminal extracellular portion can be released by proteolytic cleavage. The second isoform is a secreted form that lacks the transmembrane and intracellular portions. This assay is directed at the extracellular portion of IL-6 Receptor and detects both the soluble and membrane bound forms.

Function
Part of the receptor for interleukin 6. Binds to IL6 with low affinity, but does not transduce a signal. Signal activation necessitate an association with IL6ST. Activation may lead to the regulation of the immune response, acute-phase reactions and hematopoiesis.
Low concentration of a soluble form of IL6 receptor acts as an agonist of IL6 activity. -
Tissue specificity
Isoform 2 is expressed in peripheral blood mononuclear cells and weakly found in urine and serum. -
Sequence similarities
Belongs to the type I cytokine receptor family. Type 3 subfamily.
Contains 1 fibronectin type-III domain.
Contains 1 Ig-like C2-type (immunoglobulin-like) domain. -
Domain
The two fibronectin type-III-like domains, contained in the N-terminal part, form together a cytokine-binding domain.
The WSXWS motif appears to be necessary for proper protein folding and thereby efficient intracellular transport and cell-surface receptor binding. -
Post-translational
modificationsA short soluble form may also be released from the membrane by proteolysis. -
Cellular localization
Secreted and Basolateral cell membrane. - Information by UniProt

Example of IL-6 R alpha standard curve.Background-subtracted data values (mean +/- SD) are graphed.
-
Interpolated concentrations of IL-6 R alpha in mouse serum, plasma (citrate), and plasma (EDTA).The concentrations of IL-6 R alpha were measured in duplicate and interpolated from the IL-6 R alpha standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean IL-6 R alpha concentration was determined to be 20.9 ng/mL in mouse serum, 19.1 ng/mL in mouse plasma (Citrate), and 17.1 ng/mL in mouse plasma (EDTA).

Interpolated concentrations of IL-6 R alpha in mouse plasma (heparin), and J774A.1 cell culture supernatant.The concentrations of IL-6 R alpha were measured in duplicate and interpolated from the IL-6 R alpha standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean IL-6 R alpha concentration was determined to be 17,650 pg/mL in mouse plasma (heparin), and 849 pg/mL in J774A.1 cell culture supernatant.

Comparison of secreted IL-6 R alpha in unstimulated and PMA/PHA-stimulated J774A.1 Cells.J774A.1 cells were grown in the absence (unstimulated) or presence of Phorbol Myristate Acetate (PMA) and phytohemagglutinin (PHA) (stimulated) for 3 days. IL-6 R alpha was measured in 2-fold diluted cell culture supernatants of unstimulated and PMA/PHA stimulated J774A.1 and cell culture media. Measured values were interpolated from the IL-6 R alpha Standard Curve diluted in Sample Diluent NS and corrected for dilution factor. Mean of duplicate values +/-SD are graphed, 568 pg/mL unstimulated, 849 pg/mL stimulated, and undetectable in media.
