Title:
PROBE REAGENT AND FISH USING PROBE REAGENT
Document Type and Number:
WIPO Patent Application WO/2015/141856
Kind Code:
A1
Abstract:
The present invention provides: a probe reagent that uses a nucleic acid having a base number that is shorter than a BAC probe to minimize nonspecific adsorption and that makes it possible to stably obtain a fluorescence signal in FISH; and FISH that uses the probe reagent. The probe reagent is for in situ hybridization in which a fluorescent body-integrated nanoparticle that is obtained by integrating a fluorescent body is bound with a nucleic acid molecule of a predetermined nucleic acid sequence. As a result, nonspecific adsorption is prevented when performing FISH in which a specific area of a chromosome is stained and it is possible to improve the detection precision with respect to a specific gene, it is possible to obtain a fluorescence signal that is sufficiently intense for observation using a confocal microscope, and it becomes possible to simultaneously detect bright spots that are positioned at different depths in a tissue section from the same point of view even when observing with a fluorescence microscope when fluorescent body nanoparticles are used. In addition, it becomes possible to maintain a tissue section slide on which FISH has been performed in a state in which it is possible to detect bright spots for longer than in the prior art.
