MEASURING METHOD FOR IMMUNOLOGICALLY ACTIVE SUBSTANCE

摘要

PROBLEM TO BE SOLVED: To provide a method allowing quick, easy and highly sensitive execution capable of precluding an immunologically active substance immobilized on a carrier particle from being deactivated, and capable of precluding coexisting protein in a measuring sample from being adsorbed nonspecifically on the carrier particle, in an immunological measuring method using the carrier particle immobilized with the immunologically active substance. SOLUTION: In this measuring method for the immunologically active substance includes a process for bringing the immunologically active substance A immobilized on the particle comprising a polymer into reaction with the another immunologically active substance B in an aqueous liquid. The particle used therein is a particle of which at least the particle surface part comprises the polymer having in its side chain an aromatic group Ar having a group expressed by a general formula (1), wherein A represents an alkylene group, and R1, R2, R3represent alkyl groups which may have hydrogen atom or hydroxyl group, and a nonionic oxygen-containing group, and the reaction is carried out under the presence of a piezoelectric element.
