Filed: 1993-02-25
Abstract: PURPOSE: To simply and rapidly measure a substance to be analyzed in an aq. soln. by the flocculation of unfixed red corpuscles by thermostatically holding treated red corpuscles and a treated sample soln. CONSTITUTION: Red corpuscles are thermostatically held along with one kind or several kinds of antibodies not guiding red corpuscles to flocculation before a scheduled time and bonded to the first binding partner of a highly compatible binding pair before and after thermostatic holding. At this time, the antibodies correspond to the antigens on an erythrocyte membrane. The treated red corpuscles are thermostatically held along with the second binding partner of the highly compatible binding pair. At this time, the second binding partner is selected so as to have two or more binding positions per a molecule with respect to the first binding partner. Next, the treated red corpuscles are thermostatically held along with the first binding partner of the highly compatible binding pair bonded to an antlgenic activity determinant of an substance to be analyzed.  Further, the treated red corpuscles are thermostatically held along with a sample soln. treated with the antibodies to the substance to be analyzed and the deficiency or presence of the substance to be analyzed in the sample soln. is measured by the generation of flocculation reaction. By this method, simple and rapid measurement becomes possible.
