Abstract
Disclosed are a method for assaying a target substance in a sample and an apparatus for the method. The method can specifically assay the target substance in the sample without using any antibody against the target substance. The assaying method includes simultaneously or successively bringing a labeled aptamer, the target substance in the sample and a solid phase into contact together, and then measuring the label of the aptamer which has not been bound on the solid phase. The labeled aptamer has a property of binding to the target substance. The solid phase carries an oligonucleotide immobilized on it in an excess amount relative to the target substance. The oligonucleotide is hybridizable with the labeled aptamer when the labeled aptamer is in a state that it is not bound to the target substance, but is not hybridizable with the labeled aptamer when the labeled aptamer is in a state that it is bound to the target substance.
