Patents by Inventor Youxiang Wang

Youxiang Wang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11739375
    Abstract: The invention provides methods of digital amplification using primers of limited nucleotide composition. Limited nucleotide composition means that the primers are underrepresented in at least one nucleotide type. Such primers have much reduced capacity to prime from each other or to extend initiated by mispriming from other than at their intended primer binding sites in a target nucleic acid.
    Type: Grant
    Filed: August 10, 2018
    Date of Patent: August 29, 2023
    Assignee: ATILA BIOSYSTEMS INCORPORATED
    Inventors: Youxiang Wang, Zhijie Yang, Xin Chen, Yu Zhao, Rong Wang
  • Publication number: 20220033891
    Abstract: The invention provides methods of amplification from a single primer or a pair of forward and reverse primers of limited nucleotide composition. Limited nucleotide composition means that the primers are underrepresented in at least one nucleotide type. Such primers have much reduced capacity to prime from each other or to extend initiated by mispriming from other than at their intended primer binding sites in a target nucleic acid.

  • Patent number: 8673567
    Abstract: A method and kit for detecting the presence of a target sequence in a polynucleotide analyte contained in a sample are disclosed. In practicing the method, the sample is mixed with a single-stranded DNA target probe having a sequence capable of hybridizing with the target sequence, under conditions effective to form a double-stranded complex of the analyte and the single-stranded DNA target probe, and the single-stranded DNA target probe in the complex is reacted in the presence of a polymerase and one to three nucleotide triphosphates, to add a selected one or more target-directed nucleotide bases to single-stranded DNA target probe's 3? end to produce a modified probe. The modified probe is hybridized with a single-stranded DNA detection probe, the two probes are ligated to form a two-probe ligation product, and the presence of the ligation product is detected.

In practicing the method, the sample is mixed with a target probe having a sequence capable of hybridizing with said target sequence, under conditions effective to form a double-stranded complex of the analyte and the probe, and the probe in the complex is reacted in the presence of a polymerase and a selected one to three of four possible nucleotide triphosphates, to add a selected one or more target-directed nucleotide bases to the probe's 3? end to produce a modified probe. The modified probe is hybridized with a detection probe, the two probes are ligated to form a two-probe ligation product, and the presence of the ligation product is detected.

  • Publication number: 20050069939
    Abstract: Rolling circle amplification is used to amplify and detect target nucleic acid molecules by affixing a first and/or second linker nucleic acid molecule or a second linker nucleic acid molecule to the target nucleic acid molecule, then circularizing the target nucleic acid molecule, and then amplifying the circularized nucleic acid molecule to generate reiterated nucleic acid sequences. The methods may be used to amplify nucleic acids, particularly RNA, for detection and cloning.
