Publication number: 20220298558Abstract: Kits for detecting a mutated target base sequence are provided. For example, the kits can be for detecting a target base sequence (A) containing a nucleotide with a mutated base from a nucleic acid sample. The kits contain a fluorescent-labeled detection probe and a competitive probe combination that is to improve detection by reducing noise. The probe combination is produced using a process that includes, for example, determining the base length and the base sequence of each of the fluorescent-labeled detection probe and the competitive probe. The determining can include experimentally determining the amount to be added to the nucleic acid sample of each of the fluorescent-labeled detection probe and the competitive probe.Type: ApplicationFiled: June 6, 2022Publication date: September 22, 2022Inventors: Satoru Michiyuki, Hidetoshi Kanda

Publication number: 20220298557Abstract: Methods for designing and producing a fluorescent-labeled detection probe and a competitive probe combination are provided to improve detection by reducing noise. A method for designing the fluorescent-labeled detection probe and a competitive probe combination includes, for example, determining the base length and the base sequence of each of the fluorescent-labeled detection probe and the competitive probe. The determining can include experimentally determining the amount to be added to the nucleic acid sample of each of the fluorescent-labeled detection probe and the competitive probe. The methods provide a functional result of a first order derivative curve for the control target reaction sample having a substantial peak (maximum value), but a first order derivative curve for the control non-target reaction sample not having a substantial peak, the functional result improving detection by reducing noise.Type: ApplicationFiled: June 6, 2022Publication date: September 22, 2022Inventors: Satoru Michiyuki, Hidetoshi Kanda

Patent number: 8201700Abstract: Provided is a container 1 for inspection which stores and pours out contents therein, and the container is provided with a container main body 2 having a mouth portion 22 formed thereon, a cover portion 3 attached to the mouth portion 22 to seal the container main body 2, and an opening cap 4 attached to the cover portion 3. The cover portion 3 has a closing wall 34 for closing the mouth portion 22, and the opening cap 4 is provided with an pouring outlet 421, and a cutting portion 431 for cutting the closing wall 34. When the opening cap 4 is attached to the cover portion 3, the cutting section 431 cuts the closing wall 34 to enable pouring out the contents. Thus, in the provided container 1 for inspection, sealing properties of the container main body 2 are ensured by the cover portion 3, and the closing wall 34 of the cover portion 3 is cut by the opening cap 4 attached to the cover portion 3 without removing the cover portion 3, whereby the contents can be poured out.Type: GrantFiled: January 18, 2008Date of Patent: June 19, 2012Assignees: Toyo Seikan Kaisha, Ltd., Eiken Kagaku Kabushiki KaishaInventors: Tomoyuki Shibata, Manabu Hosokawa, Hiroaki Hayashi, Natsuki Masuya, Yoshiaki Seto, Shingo Saito, Hidetoshi Kanda
