Abstract
A method of storing fluorescent dye-containing resin particles comprising adding the fluorescent dye-containing resin particles in a liquid comprising a buffer, a protein, and a surfactant, thereby obtaining a particle-containing liquid. The rate of change in the backscatter intensity (transmitted light) at the center of the height of the particle-containing liquid left to stand for 24 hours after the adding is not less than −1% based on the particle-containing liquid immediately after the adding.
