摘要：
An object of the present invention is to provide a latex particle for a measurement reagent with which highly sensitive measurement can be performed even in measuring a measurement sample containing a test substance in a dilute concentration.The preset invention relates to a latex particle for a measurement reagent including a copolymer obtained by copolymerizing a monomer mixture containing the following polymerizable monomers (a) to (c): (a) a polymerizable monomer having a phenyl group; (b) a polymerizable monomer having a phenyl group and a sulfonate; and (c) a polymerizable monomer having a naphthyl group, in an aqueous medium containing 7.5 to 25% by weight of C1-4 alcohol without using a surfactant.
