Nucleic acid element for use in analysis, and analytical method, analytical reagent and analytical instrument using same

摘要

The technique by which simple analysis of an intended subject to be analyzed can be carried out is provided. In this technique, a nucleic acid element 16 for use in analysis including: a first nucleic acid part 12; and a second nucleic acid part 13 is used. In the nucleic acid element 16, the first nucleic acid part 12 is a binding part that can bind to a subject 11 to be analyzed, and the second nucleic acid part 13 is a labeling part that can distinguish between binding and non-binding of the first nucleic acid part 12 to the subject 11. It is preferred that the first nucleic acid path 12 is an aptamer against the subject 11. The subject I 11 can be analyzed easily by using the nucleic acid element 16, binding the subject 11 to the first nucleic acid part 12, and then analyzing the binding with the second nucleic acid part 13,
