Abstract
A latex particle for high-sensitive agglutination assay and a reagent for agglutination assay including the particle are provided. The latex particle barely initiates non-specific reactions and can readily prepare diagnostic agents. A latex particle for agglutination assay including a polymerizable monomer having a phenyl group, a polymerizable monomer having a phenyl group and a salt of sulfonic acid, and a polymerizable monomer represented by Formula (1):CH═CR—COO(CHCHO)—R  (1)where Rrepresents a hydrogen atom or a methyl group; Rrepresents a hydrogen atom or a methyl group; and n is 1≦n<20, wherein the density of functional groups derived from the polymerizable monomer represented by Formula (1) on the surface of the particle is 0.05 to 0.5 μmol/m.
