Patent number: 11154856Abstract: A test device includes a housing and a lid. The housing encloses an internal space, has a hole supporting a container accommodating liquid, and includes a perforation/incision part. The lid covers a hole-formed part of the housing. The housing and/or the lid includes a guide that guides the housing and the lid, so that the lid can migrate from the first position to the second position while covering the hole-formed part of the housing. In the first position, the lid covers the hole-formed part of the housing and the container and the container is not incised. During the migration of the lid from the first position to the second position, the container is pushed toward the perforation/incision part by the lid, and the container is incised to leak liquid into the internal space.Type: GrantFiled: January 28, 2019Date of Patent: October 26, 2021Assignee: KANEKA CORPORATIONInventors: Sotaro Sano, Shigehiko Miyamoto, Takaaki Jikihara

Patent number: 10829805Abstract: An object of the invention is to provide a nucleic acid detection method which takes advantage of the high specificity of hybridization techniques, reduces the time length and the number of steps required for detection of PCR products, and allows for easy and highly accurate detection by visual observation without the need of special equipment; and a nucleic acid detection device or kit. The invention provides a method for detecting a target nucleic acid in a sample, which includes performing amplification of the target nucleic acid sequence to synthesize an amplification product having a partially double-stranded structure where a single-stranded region is added to each end of the target sequence, and hybridizing a nucleic acid sequence bound to a development medium and a nucleic acid sequence labeled with a labeling compound with the single-stranded regions of the amplification product to form a sandwich hybridization complex; and a detection device thereof.Type: GrantFiled: February 2, 2018Date of Patent: November 10, 2020Assignee: KANEKA CORPORATIONInventors: Koji Takahashi, Shigehiko Miyamoto, Takaaki Jikihara, Jun Tomono
