<p>[Problem] To provide a pathological stain solution used for immunofluorescence staining, the pathological stain solution comprising a liquid dispersion in which fluorescent nanoparticles do not precipitate even when the pathological stain solution has been stored for one month. [Solution] A pathological stain solution comprising a liquid dispersion including a solvent and a fluorescent marker which comprises fluorescent nanoparticles having an average particle diameter of 50-200 nm, the liquid dispersion satisfying formula (1). Formula (1): (ρ－ρw）／η≰０．０２ (In formula (1),ρrepresents the solid density (g/cm3) of the fluorescent nanoparticles,ρw represents the density (g/cm3) of the liquid dispersion at 20°C, andηrepresents the viscosity (ｇ／ｃｍ・ｓｅｃ) of the liquid dispersion at 20°C.)</p> |
