Abstract
Latex particles for a particle agglutination assay, with which it is possible to carry out high-sensitivity assay while highly suppressing a non-specific reaction are disclosed. The latex particles being obtained by emulsion polymerization with a polymerizable monomer having a phenyl group, and a polymerizable monomer having a phenyl group and a sulfonate in an aqueous medium including a nonionic surfactant at a concentration of 0.005 to 0.02 wt % based on the aqueous medium, the latex particles having an average particle size of 0.005 to 1.0 μm.
