摘要:
A naturally-occurring soluble truncated IL-23Rα protein (i.e., Δ9 IL-23Rα) is shown to be present in a biological sample and can serve as a diagnostic tool for autoimmune diseases. There is provided an enzyme-linked immunosorbent assay (ELISA) and test kit for the serological detection of the soluble truncated form of IL-23Rα protein. More particularly, antibody-sandwich ELISA method and kits for Δ9 IL-23Rα as an antigen were developed to detect Δ9 IL-23Rα levels in biological samples from a mammal and a human patient and are used as a diagnostic index. The present disclosed ELISA has utility as a diagnostic tool to detect Crohn's disease in patients using EDTA-plasma.
