AGGLUTINATION ENHANCER

摘要

The purpose of the present invention is to provide an agglutination enhancer which has a superior agglutination enhancing effect to those of conventional immunoagglutination enhancers. An agglutination enhancer for use in an immunoagglutination measurement method, which comprises a polymer having a monomer unit represented by general formula [1] (wherein R1 represents a hydrogen atom or a methyl group; R2 and R3 independently represent a methyl group or an ethyl group; X represents -NH-or an oxygen atom; n represents an integer of 1-6; and m represents an integer of 1-3): and an immunoagglutination measurement method comprising bringing an antibody against an analyte (a substance to be measure) or an antigen for the analyte into contact with the analyte in the co-presence of the above-mentioned agglutination enhancer for use in an immunoagglutination measurement method to thereby cause an antigen-antibody reaction.
