Abstract
An objective of the invention is to provide a carrier particle latex for an assay reagent capable of assaying a biological sample at a wide range of the concentration in an immunoserological test and capable of being stored stably for a prolonged period, as well as an assay reagent employing the same. The invention is a carrier particle latex for an assay reagent comprising a carrier particle comprising a copolymer of a polymerizable monomer having a phenyl group and a polymerizable monomer having a phenyl group and a sulfonate, wherein said carrier particle has a surface sulfonic acid group amount of 0.005 to 0.7 μmol/m2 and an average particle size of 0.01 to 1.5 μm.
