Abstract: The present invention is intended to provide a novel fluorescence sensor for target analysis, a kit for target analysis, and a target analysis method using the same. The fluorescence sensor for target analysis according to the present invention includes a nucleic acid molecule that includes a G-quartet-forming nucleic acid region (D) that forms a G-quartet and a binding nucleic acid region (A) that binds to a target. In the absence of a target, formation of a G-quartet in the G-quartet-forming nucleic acid region (D) is inhibited. In the presence of a target, the target comes into contact with the binding nucleic acid region (A), the G-quartet is formed in the G-quartet-forming nucleic acid region (D) due to the contact, the G-quartet-forming region (D) and porphyrin forms a complex, and the complex generates fluorescence.

Abstract: The present invention provides a novel nucleic acid molecule that can be used for detection of peanuts. The peanut-binding nucleic acid molecule of the present invention is characterized in that it binds to a peanut allergen with a dissociation constant of 10 nM or less, and preferably contains a polynucleotide consisting of any of base sequences of SEQ ID NOs: 1 to 15, for example. It is also preferable that, for example, the peanut-binding nucleic acid molecule of the present invention binds with significant specificity to the peanut allergen rather than to a soybean protein.
