<p>The purpose of the present invention is to provide a carrier for immobilizing a material having a PEG linker that expresses high detection sensitivity in the ELISA. The present invention pertains to a carrier for immobilizing a material for use in an immunoassay, and said carrier for immobilizing a material includes at least a substrate and a hydrophilic polymer layer that is positioned on the surface of the substrate. The hydrophilic polymer layer contains polyethylene glycol chains, and functional groups that are linked to the polyethylene glycol chains, said functional groups being capable of forming covalent bonds with the material being immobilized, which is an antigen or antibody that bonds with a target substance, or which is a target substance. The present invention also pertains to a method for immobilizing a material to be immobilized in said carrier, and a method and kit for carrying out measurements by immunoassays in which said carrier is used.</p> |
