The present invention provides a new target analysis method and a target analysis kit for use in the method. The target analysis method of the present invention includes: causing a specimen, a labeled binding nucleic acid molecule that binds to a target, and a carrier on which a blocking nucleic acid molecule that binds to the labeled binding nucleic acid molecule is immobilized to react; separating a fraction of the carrier and a fraction of components other than the carrier from each other; and detecting a label of the labeled binding nucleic acid molecule in at least one of the fraction of the carrier and the fraction of components other than the carrier to analyze a target in the specimen.

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.

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.

摘要:
The present invention is to provide a new sensor for melamine detection. The nucleic acid sensor for melamine analysis of the present invention includes a polynucleotide (xl) that includes a catalytic nucleic acid molecule (D) that activates a catalytic function and a binding nucleic acid molecule (A) that binds to melamine. The polynucleotide (xl) has any one of the base sequences of SEQ ID NOs: 1 to 14, and n and m are positive integers. In the nucleic acid sensor, since the catalytic function of the catalytic nucleic acid molecule (D) is inhibited in the absence of melamine and the catalytic function of the catalytic nucleic acid molecule (D) is activated in the presence of melamine, melamine can be analyzed by detecting the catalytic function.
