摘要
The present invention relates to latex particles for measurement reagents, said latex particles having a coefficient of variation in particle diameters of 10% or less and an average particle diameter of 250 to 1000 nm. Each of the latex particles contains 20% by weight or more of a compound having a refractive index of 1.60 or more. The depth of a supernatant is 5 mm or less when a liquid dispersion having a solid matter concentration of 1% by weight, which is prepared by dispersing the latex particles in ultrapure water, is placed in a tubular 10-ml measuring cylinder having a body inner diameter of 10.8 mm and is then allowed to leave for 10 days. According to the particles, a measurement of a measurement sample can be performed at a high sensitivity even when the concentration of a substance to be tested in the measurement sample is low.
