Product 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 sR 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).

Precision
Intra-Assay Precision (Precision within an assay)
Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays)
Three samples of known concentration were tested in separate assays to assess inter-assay precision.

- Background
- IL-6 Receptor alpha
- The multifunctional factor interleukin 6 (IL-6) exerts its activities through binding to a high-affinity receptor complex consisting of two membrane glycoproteins: an 80 kDa component receptor that binds IL-6 with low affinity (IL-6 R) and a signal-transducing component of 130 kDa (gp 130) that does not bind IL-6 by itself, but is required for high-affinity binding of IL-6 by the complex. A soluble form of the IL-6 R alpha has been found in the urine of healthy adult humans. This soluble receptor apparently arises from proteolytic cleavage of membrane-bound IL-6 R alpha. No naturally-occurring mRNA encoding a truncated form of the IL-6 R alpha has been reported. Soluble forms of human and murine IL-6 R alphas have been constructed, however, by insertion of termination codons into the regions of the IL-6 R alpha cDNAs encoding the external portions of the receptors and prior to the transmembrane domains. These soluble receptors have been expressed in COS-7 and CHO cells and have been shown to bind to IL-6 in solution and to augment the activity of IL-6 as a result of the binding of the IL-6/IL-6 R alpha complex to membrane-bound gp130.
