Patent number: 9097718Abstract: The present invention provides a method for detecting a nucleic acid, by which a multi-stranded nucleic acid amplified by a nucleic acid amplification method is detected easily and with a high degree of accuracy without the need for specialized equipment, and also provides a nucleic acid detection device. Provided are a method for detecting a nucleic acid under visible light via a color reaction produced by contact between a chromogenic leuco dye and the multi-stranded nucleic acid, as well as a nucleic acid detection device using this method.Type: GrantFiled: September 21, 2011Date of Patent: August 4, 2015Assignee: Kaneka CorporationInventors: Shigehiko Miyamoto, Takaaki Jikihara, Sotaro Sano, Koji Takahashi, Jun Tomono

Patent number: 9005985Abstract: This invention provides compositions that have a light emitting reporter linked to biomolecules, preferably, nucleotide oligomers. The light reporter particles are silylated and functionalized to produce a coated light reporter particle, prior to covalently linking the biomolecules to the light reporter particle. The light reporter particles of the invention can be excited by a light excitation source such as UV or IR light, and when the biomolecule is DNA, the attached DNA molecule(s) are detectable by amplification techniques such as PCR.Type: GrantFiled: February 7, 2013Date of Patent: April 14, 2015Assignee: APDN (B.V.I.) Inc.Inventors: Thomas Kwok, Benjamin MingHwa Liang, Stephane Shu Kin So

Methods and assays for the detection of alternative lengthening of telomeres (ALT) activity in cells
Patent number: 8999643Abstract: The invention relates to methods and assays for the detection of active Alternative Lengthening of Telomeres (ALT) activity in cells. The methods and assays involve detecting or assaying for partially double-stranded telomeric circles wherein the presence of said circles is specific for cells comprising an active ALT mechanism. In some embodiments the methods find application in, inter alia, determining the level of ALT activity in a cell, determining the ALT status of a cancer in a subject, diagnosing and/or treating disease, determining disease status, analysis of treatment efficacy, and the identification of novel therapeutic agents.Type: GrantFiled: September 21, 2010Date of Patent: April 7, 2015Assignee: Children's Medical Research InstituteInventors: Roger Robert Reddel, Jeremy David Henson
