  • Publication number: 20220298558
    Abstract: 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.

  • Publication number: 20220298557
    Abstract: 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.

  • Publication number: 20140308663
    Abstract: The object of the present invention is to provide a method that allows stable amplification of an internal standard material while maintaining an accurate assay value for a target nucleic acid in a nucleic acid detection system involving the use of an internal standard material and a reagent kit used therefor. The present invention relates to a method for nucleic acid amplification comprising preventing an internal standard amplification product from affecting amplification reaction of a target nucleic acid by performing amplification of an internal standard material prior to amplification of the target nucleic acid in the method for amplifying a target nucleic acid in a sample using an internal standard material and a reagent and reagent kit used therefor.

  • Patent number: 8201700
    Abstract: 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.

  • Patent number: 7638280
    Abstract: The method of the present invention is based on a method wherein a nucleic acid is synthesized utilizing the hybridized 3?-end, which is synthesized by complementary strand synthesis, on a specific region of a target nucleotide sequence existing as the nucleotide sequence of the same strand as the origin for the next round of complementary strand synthesis. The hybridization to a specific region, which region is searched for mutations and polymorphisms, is repeatedly carried out according to the present invention. Thus, mutations and polymorphisms in a target nucleotide sequence are exactly copied to the reaction products.
