  • Publication number: 20230295718
    Abstract: The present invention relates to a method for the highly specific, targeted capture of regions of human genomes and transcriptomes from the blood, i.e. from cell free circulating DNA, exosomes, microRNA, circulating tumor cells, or total blood cells, to allow for the highly sensitive detection of mutation, expression, copy number, translocation, alternative splicing, and methylation changes using combined nuclease, ligation, polymerase, and massively parallel sequencing reactions. The method generates a collection of different circular chimeric single-stranded nucleic acid constructs, suitable for sequencing on multiple platforms. In some embodiments, each construct of the collection comprised a first single stranded segment of original genomic DNA from a host organism and a second single stranded synthetic nucleic acid segment that is linked to the first single stranded segment and comprises a nucleotide sequence that is exogenous to the host organism.

  • Patent number: 10830757
    Abstract: The present invention is directed to methods comprising a device that comprises a biomolecular processor and one or more nanotubes. Each biomolecular processor comprises a bioreactor chamber defined by a solid substrate, a plurality of spaced support structures within said bioreactor chamber and attached to the solid substrate, one or more nanotubes defined by the solid substrate and fluidically coupled to the bioreactor chamber and one or more capture molecules immobilized to some or all of said plurality of spaced support structures, said one or more capture molecules suitable to bind to a portion of a target nucleic acid molecule in a sample. The nanotubes have a passage extending between an input end proximate to the bioreactor chamber and an output end distal to the bioreactor chamber, and comprises one or more nanopores within the passage with each nanopore having a reduced diameter relative to the passage.

  • Patent number: 10829804
    Abstract: The present invention is directed methods for identifying, in a sample, one or more target nucleotide sequences differing from other nucleotide sequences in the sample by one or more nucleotides, one or more copy numbers, one or more transcript sequences, and/or one or more methylated residues, using ligation detection reactions, polymerase mediated extension reactions, and/or cleavage reactions. The present invention is also directed to methods for identifying, in a sample, one or more nucleotides in a target nucleotide sequence.
