Patents by Inventor James R. Prudent

James R. Prudent 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).

  • Materials and methods for detection of nucleic acids
    Publication number: 20020150900
    Abstract: Assays using non-natural bases are described. In one embodiment, the method involves contacting a sample suspected of containing the target nucleic acid with a polymerase and first and second primers; amplifying the target nucleic acid, if present in the sample, by PCR using the first and second primers to generate an amplification product having a double-stranded region and a single-stranded region that comprises the non-natural base; contacting the sample with a reporter comprising a label and a non-natural base that is complementary to the non-natural base of the single-stranded region; annealing at least a portion of the reporter to the single-stranded region of the amplification product; cleaving, after annealing, at least a portion of the reporter to release at least one reporter fragment; and correlating the release of the at least one reporter fragment with the presence of the target nucleic acid in the sample.

  • Invasive cleavage of nucleic acids
    Patent number: 6348314
    Abstract: The present invention relates to means for the detection and characterization of nucleic acid sequences, as well as variations in nucleic acid sequences. The present invention also relates to methods for forming a nucleic acid cleavage structure on a target sequence and cleaving the nucleic acid cleavage structure in a site-specific manner. The structure-specific nuclease activity of a variety of enzymes is used to cleave the target-dependent cleavage structure, thereby indicating the presence of specific nucleic acid sequences or specific variations thereof.

  • Polymorphism analysis by nucleic acid structure probing
    Patent number: 6214545
    Abstract: The present invention relates to methods and compositions for analyzing nucleic acids. In particular, the present invention provides methods and compositions for the detection and characterization of nucleic acid sequences and sequence changes. The methods of the present invention permit the detection and/or identification of genetic polymorphism such as those associated with human disease and permit the identification of pathogens (e.g., viral and bacterial strain identification).
