Abstract:
An object of the present invention is to provide: a staining agent for tissue staining which has an improved fluorescence signal evaluation accuracy; and a tissue staining kit comprising the staining agent. The staining agent for tissue staining contains, as a staining component, dye-resin particles comprising thermosetting resin particles and a fluorescent dye immobilized on the resin particles, wherein the resin particles contains a substituent having an electric charge opposite to that of the fluorescent dye and forms an ionic bond or a covalent bond with the fluorescent dye, and the dye-resin particles have a particle size variation coefficient of 15% or less.

Claim (Index 1):
A method of producing a staining agent for tissue staining, comprising the step of adjusting the variation coefficient of said dye-resin particles to be 15% or less by adding a surfactant to a reaction system used for producing said resin particles through a synthesis reaction.
