COMPOSITION THAT RECOGNIZES ANTIBODIES STEMMING FROM IMMUNE-MEDIATED PERIPHERAL NEUROPATHY AND USE FOR SAID COMPOSITION

摘要

Sugar-chain-immobilized fluorescent nanoparticles that allow quick and convenient detection of ganglioside-binding autoantibodies in blood serum from immune-mediated peripheral neuropathy patients are provided, as is a use for said sugar-chain-immobilized fluorescent nanoparticles. These sugar-chain-immobilized fluorescent nanoparticles contain the following: sugar-chain ligand complexes comprising sugar chains, including ganglioside-derived sugar chains, and a prescribed linker compound that has a hydrocarbon chain or the like on the main chain thereof; and fluorescent nanoparticles that have a prescribed core-shell structure. These sugar-chain-immobilized fluorescent nanoparticles are obtained by immobilizing the abovementioned sugar chains.
