METHOD OF DETECTING TARGET SUBSTANCE

摘要

Provided are a method of detecting a target substance and the like using a probe with a simple design for target substance detection. The method of detecting a target substance of the present invention includes a step of providing a probe 4 in which an aptamer-bindable substance 1 and a labeling substance 2 are each bound to a linker 14 that is immobilizable to a support 5 and an aptamer 6 is bound to the aptamer-bindable substance 1; and a step of detecting separation of the aptamer 6 based on the labeling substance 2 by separating the aptamer 6 from the aptamer-bindable substance 1 through binding between a target substance 8 in a sample and the aptamer 6 wherein the probe 4 is immobilized to the support 5.
