Abstract: Provided are: a photocoupling method that overcomes the problem of the stagnation of photocoupling with a target nucleotide using a probe containing a photo-responsive nucleotide, and that improves the photocoupling efficiency; and a photocoupling kit. The photocoupling method is characterized by hybridizing a target site present in a nucleic acid sample with a first probe having a sequence complementary to the target site and containing a photo-responsive nucleotide, in a reaction solution, and carrying out photocoupling by photo-irradiation, wherein self-assembly caused by the photo-responsive nucleotide contained in the first probe is suppressed. The photocoupling kit is characterized by comprising a first probe having a sequence complementary to a target site present in a nucleic acid sample, and containing a photo-responsive nucleotide; and a second probe being highly complementary to the first probe.

Abstract: Provided is a specimen slide for genetic testing, by which: (1) a step for scraping off an FFPE section from an unstained slide can be simplified without affecting the subsequent nucleic acid extraction step; (2) the risk of contamination when scraping off can be avoided; and (3) a cancer site can be selectively separated by an inexpensive and simple means. The specimen slide for genetic testing is a specimen slide for genetic testing on which a specimen section is to be mounted, wherein part of the slide can be separated, together with the specimen section to be separated, from the rest of the slide, while maintaining an upper surface and a lower surface of the slide.
