Human IL-6R alpha Quantikine ELISA Kit Summary

The Quantikine Human IL-6 sR Immunoassay is a 4.5 hour solid phase ELISA designed to measure human IL-6 sR in cell culture supernates, serum, plasma, and urine. It contains recombinant human IL-6 sR produced in Sf 21 cells and antibodies raised against this protein. This kit has been shown to accurately quantitate the recombinant soluble IL-6 R. Results obtained using natural IL-6 s...R showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural IL-6 sR. Since the measurement of human IL-6 sR by this immunoassay is insensitive to added recombinant human IL-6, it is probable that this measurement corresponds to the total amount of the soluble receptor present in samples ( i.e. the total amount of free receptor plus the total amount of receptor bound to IL-6).

IL-6 R alpha is a transmembrane subunit of the receptor for Interleukin-6. It associates with gp130 which is a shared component of the receptors for CLC, CNTF, CT-1, IL-11, IL-27, LIF, and OSM. Soluble forms of IL-6 R alpha are generated by both alternative splicing and proteolytic cleavage. In a mechanism known as trans-signaling, complexes of soluble IL-6 and IL-6 R alpha elicit responses from gp130-expressing cells that lack cell surface IL-6 R alpha. IL-6 plays important roles in the acute phase reaction, inflammation, hematopoiesis, bone metabolism, and cancer progression. IL-6, along with TNF-alpha and IL-1, drives the acute inflammatory response and the transition from acute inflammation to either acquired immunity or chronic inflammatory disease. When dysregulated, it contributes to chronic inflammation in obesity, insulin resistance, inflammatory bowel disease, arthritis, sepsis, and atherosclerosis.
