DEVICE FOR ASSAYING SELECTIVELY-BINDING SUBSTANCE AND AGENT FOR IMMOBILIZING POLYPEPTIDE

摘要

PROBLEM TO BE SOLVED: To provide a device for assaying a selectively-binding substance such as an antigen in which a polypeptide such as an antibody is accurately immobilized to a specific site of a microchannel. SOLUTION: In the device for assaying a selectively binding substance such as an immunoassay device in which a polypeptide is bound to a desired site in the microchannel by a covalent bond via a linker structure, the polypeptide selectively binds to a substance with a biological origin such as an antibody, and the linker includes a benzophenone structure; a hydrophilic region such as polyethylene glycol; and a carboxyl group in this order.
