  • Patent number: 11970740
    Abstract: Next Generation DNA sequencing promises to revolutionize clinical medicine and basic research. However, while this technology has the capacity to generate hundreds of billions of nucleotides of DNA sequence in a single experiment, the error rate of approximately 1% results in hundreds of millions of sequencing mistakes. These scattered errors can be tolerated in some applications but become extremely problematic when “deep sequencing” genetically heterogeneous mixtures, such as tumors or mixed microbial populations. To overcome limitations in sequencing accuracy, a method Duplex Consensus Sequencing (DCS) is provided. This approach greatly reduces errors by independently tagging and sequencing each of the two strands of a DNA duplex. As the two strands are complementary, true mutations are found at the same position in both strands. In contrast, PCR or sequencing errors will result in errors in only one strand.

  • Publication number: 20240124867
    Abstract: The disclosure provides methods and related kits, reagents, and systems for selectively deaminating unmethylated cytosine residues in nucleic acid molecules. In some embodiments, the methods and related kits, reagents, and systems are applied for methods of detecting and/or mapping methylated cytosine residues in nucleic acids. The nucleic can be RNA or DNA. Some embodiments include contacting the polynucleic acid with a bacterial cytosine deaminase, for example DddA or SsdA, or functional fragments or derivatives thereof. Representative DddA and SsdA have sequences set forth in SEQ ID NOS:1 and 2, respectively. The bacterial cytosine deaminases of the disclosure are sensitive to methylation and, thus, deaminate only unmethylated cytosines to provide a cytosine to uracil conversion. The conversion can be detected as a C•G-to-T•A transitions in subsequent sequencing analysis.

  • Patent number: 11962671
    Abstract: Examples of biomimetic codecs and biomimetic coding techniques are described herein. Morphologically-adaptive coding networks can be developed in accordance with energy dissipation driven “heat” generated by application of training data. The morphologically-adaptive coding networks may be representative of common features expected in an input signal or data stream. Decoding may proceed using the morphologically-adaptive coding network. Morphologically-adaptive coding networks may be used as a cortex that can be shared for boosting multimedia data compression rates and/or increasing the encode-decode fidelity of information content while the features remain queryable in encoded form. Examples of the biomimetic codecs and biomimetic coding techniques provide a broad-based technology platform that can be used in context-IDed multimedia storage, pattern recognition, and high-performance computing/big data management, the hallmarks of web- and cloud-based systems.

  • Patent number: 11959133
    Abstract: The present disclosure generally relates to the methods and compositions to efficiently analyze polymer characteristics using nanopore-based assays. Specifically disclosed is a method for generating reference signals for polymer analysis in a nanopore system, wherein the nanopore system has a multi-subunit output signal resolution. The method comprises translocating a reference sequence through a nanopore to generate a plurality of reference output signals, wherein each possible multi-subunit sequence that can determine an output signal appears only once in the reference sequence. The output signals are compiled into a reference map for nanopore analysis of an analyte polymer. Also provided are methods and compositions for calibrating the nanopore system for optimized polymer analysis.

  • Publication number: 20240085372
    Abstract: Methods for nanopore-based protein analysis are provided. The methods address the characterization of a target protein analyte, which has a dimension greater than an internal diameter of the nanopore tunnel, and which is also physically associated with a polymer. The methods further comprise applying an electrical potential to the nanopore system to cause the polymer to interact with the nanopore tunnel. The ion current through the nanopore is measured to provide a current pattern reflective of the structure of the portion of the polymer interacting with the nanopore tunnel. This is used as a metric for characterizing the associated protein that does not pass through the nanopore.
