Patents by Inventor John J. Boyce, IV

John J. Boyce, IV 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).

  • Publication number: 20110027790
    Abstract: The disclosure provides methods of reducing the range of representation levels of nucleic acid targets. The methods are particularly useful for multi-target analyses benefiting from a low variance of target representations, such as, e.g., single molecule sequencing and/or heterozygous genotyping, and pathogen diagnosis. Two general methods are provided. In Method 1, starting concentrations of probes are adjusted. In Method 2, target-specific probes are “binned,” i.e., several subsets of probes are selected based on similar representation levels. Thereafter, each subset of corresponding targets is extracted, with or without amplification, using a separate portion of the sample (i.e., separate vessels).

  • Publication number: 20090156412
    Abstract: The disclosure provides methods of capturing target nucleic acids (e.g., gene or gene fragments) onto a solid support for further analysis. The disclosed methods utilize a capture probe that selectively circularizes only the target nucleic acid. Following the circularization of the target, the linear, non-target, nucleic acids are removed from the sample. Next, the circularized target is linearized and bound to a solid support. To allow for linearization, the capture probe may include a cleavage site that can be a noncanonical nucleotide(s) (e.g., uracil in DNA) and/or a rare-cutter site (e.g., the Not I restriction site). In some embodiments, the target nucleic acid is captured onto a support without an intermediate amplification step.
