Method for producing purified product of protein modified fluorescent substance particle, method for producing fluorescent staining liquid, purified product of protein modified fluorescent substance aggregated particle, fluorescent dyeing liquid and filter for purification of protein modified fluorescent substance particle

摘要

The present invention relates to a method for producing a purified protein-modified phosphor-integrated particle, a method for producing a fluorescent staining solution, a purified protein-modified phosphor-integrated particle, a fluorescent staining solution, and a filter for purifying protein-modified phosphor-integrated particles. The method for producing a purified product of the protein-modified phosphor-aggregated particles comprises the steps of: collecting a phosphor-aggregated particle (protein-modified phosphor-aggregated particle) whose surface is modified with a biological substance-binding protein; Is brought into contact with a filter supporting a substance having a reversible binding ability to the biological substance-binding protein (protein-binding substance), whereby the protein-modified phosphor-collected particles are removed from the contaminants. Including a purification step for separation.
