<p>According to the present invention, precipitation of a reactive substance-bound microparticle can be prevented in a dispersion liquid, to make a concentration of the reactive substance-bound microparticle uniform in the dispersion liquid. The present invention provides a method of preventing precipitation of a reactive substance-bound microparticle. The method includes coexisting at least one selected from the group consisting of polyanion or its salt, dextran, cyclodextrin, polyethylene glycol, and glycerol, with the microparticle in a dispersion liquid.</p> |
