PARTICLE COMPOSITE AND PROCESS FOR PRODUCING PARTICLE COMPOSITE

摘要

It is an object of the present invention to provide a particle complex that is dispersible in a liquid sample containing a target substance, and that comprises a first particle on which a reactive substance capable of reacting with a target substance is immobilized and a second particle labeled with a labeling substance, and wherein it is effectively prevented that the second particle will become a steric hindrance and decrease the efficiency of the reaction between the reactive substance and the target substance, and to achieve the object, the present invention provides a particle complex wherein a first particle on which a reactive substance capable of reacting with a target substance is immobilized and a second particle labeled with a labeling substance are immobilized on the surface of a solid support that is dispersible in a liquid sample containing the target substance.
