Target substance detection method and reagent

Abstract

A technique that can detect a target substance in a sample with higher sensitivity and at lower cost than a conventional technique is provided, which is a target substance detection method including: in a first reaction field, forming a complex by sandwiching a target substance between a first trapping substance immobilized on a solid phase and a second trapping substance labeled with the labeling substance, and separating a moiety including the labeling substance from the complex and moving it through a liquid filled in a tubular channel by a centrifugal force; and detecting the moiety including the labeling substance by light scattered by the moiety including the labeling substance.

Dependencies are inferred from the claim text.
