The proinflammatory cytokine IL-6 binds to the membrane bound or soluble IL-6 receptor (IL-6R) and activates an intracellular signaling cascade after complex formation with two gp130 molecules. These mediate general homeostasis and orchestrates the immune response during disease. Trans-signalling via the soluble IL-6R has importance for the development and maintenance of human diseases like Crohn's disease, peritonitis and rheumatoid arthritis. We have developed an enzyme-linked immunoabsorbent assay (ELISA) that detects the binding of gp130 to the IL-6/sIL-6R complex. Competitive binding of sgp130-Fc, viral IL-6, and the inhibitory drug Suramin to gp130 has been demonstrated. The assay can be used for high-throughput screening of peptide and chemical compound libraries for the identification of new agonists and antagonists of the binding between gp130 and IL-6/sIL-6R.
