摘要:
A method for detecting a target substance is described, which comprises the steps of: forming a first complex comprising (a) a first nucleic acid probe immobilized on a first solid phase and having a single-strand portion, (b) a nucleic acid ligand which has a binding section as a base sequence hybridizable with the single-strand portion of the first nucleic acid probe and which has a target-binding substance capable of binding to the target substance, (c) the target substance, and (d) a labeling substance capable of binding to the target substance; separating, from the first complex, a second complex comprising the nucleic acid ligand, the target substance and the labeling substance; and detecting the target substance on the basis of the labeling substance in the second complex.

摘要:
In detecting a nucleic acid by using the nucleic acid amplification method, it is intended to shorten the time required for the measurement so as to systematically and efficiently examine a gene, etc. To achieve this object, use is made of a method of directly amplifying a nucleic acid by treating a collected biological sample wherein a means of inhibiting the degradation activity of the nucleic acid is introduced during or after the step of homogenizing the biological sample and thus the nucleic acid is directly amplified without isolating/purifying the nucleic acid component from the biological sample. In this method, the means of inhibiting the degradation activity of the nucleic acid is introduced at an acidic pH value (more specifically, from pH 2.5 to pH 5) with the use of a salt interacting with a substance inhibiting the nucleic acid amplification reaction and/or the nucleic acid component so as to directly amplify the nucleic acid without isolating/purifying the nucleic acid component.
