    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a carboxy group-containing particle having excellent magnetic separability and a large amount of particle bonded to an organism-related substance. SOLUTION: The carboxy group-containing particle is produced by reacting the hydroxy group of a hydroxy group-containing organic polymer particle with a carboxylic acid anhydride to form an ester bond. The carboxy group-containing particle is produced by reacting a hydroxy group derived from the 2,3-hydroxypropyl group of a 2,3-hydroxypropyl group-containing organic polymer particle with a carboxylic acid anhydride.
