Patents by Inventor Kiyotada Nunomura

Kiyotada Nunomura 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: 6908735
    Abstract: Methods useful for improving results obtained with enzyme-based polynucleotide amplification reactions. More particularly, the invented methods are useful for: (1) promoting amplification of template-specific products such that the amount of amplicon produced reflects the pre-amplification amount of analyte, even in reactions primed with low levels of analyte polynucleotide; (2) facilitating biological specimen processing such that the amount of amplicon produced in subsequent amplification reactions will be substantially independent of the efficiency of analyte polynucleotide isolation from the specimen; and (3) controlling the amount of analyte amplicon produced in the amplification reaction.
    Type: Grant
    Filed: August 30, 2001
    Date of Patent: June 21, 2005
    Assignee: Gen-Probe Incorporated
    Inventor: Kiyotada Nunomura
  • Patent number: 6610475
    Abstract: The present invention features kits for making available a desired nucleic acid contained in a biological sample. The kits contain an acid for acidifying the biological sample to a pH at which endogenous nucleases capable of degrading desired nucleic acids are inactive and an acid protease able to digest cellular materials in the biological sample to release nucleic acid and to inactivate endogenous nucleases which may be present.

  • Patent number: 6534273
    Abstract: A method for capturing a target polynucleotide in a sample onto a solid support with an attached immobilized probe by using a capture probe and two different hybridization conditions that control the order of hybridization, where the first hybridization condition allows hybridization of the capture probe to the target polynucleotide, and the second hybridization condition allows hybridization of the capture probe to the immobilized probe. The method further includes amplifying the captured target polynucleotide by hybridizing at least one primer oligonucleotide to the target polynucleotide and using nucleic acid amplification that initiates from the primer oligonucleotide.

More particularly, the invented methods are useful for: (1) promoting amplification of template-specific products such that the amount of amplicon produced reflects the pre-amplification amount of analyte, even in reactions primed with low levels of analyte polynucleptide; (2) facilitating biological specimen processing such that the amount of amplicon produced in subsequent amplification reactions will be substantially independent of the efficiency of analyte polynucleotide isolation from the specimen; and (3) controlling the amount of analyte amplicon produced in the amplification reaction.

  • Patent number: 5386024
    Abstract: Method for making available a desired nucleic acid contained in a biological sample, comprising the steps of acidifying said biological sample to a pH at which endogenous nucleases capable of degrading the desired nucleic acid(s) are inactive, contacting said biological sample with an exogenous acid protease active at said pH, incubating said sample until endogenous nuclease activities are reduced to insignificant levels, and raising the pH of the biological sample to a pH sufficient to render the exogenous protease less active.
