  • Patent number: 12270125
    Abstract: The present disclosure provides a method of preparing a library of nucleic acids having modular end sequences. The method includes combining a pool of different modular nucleic acid tags with a nucleic acid sample, the nucleic acid sample including a plurality of double-stranded target nucleic acids. The method further includes joining the ends of each of the double-stranded target nucleic acids to tags selected from the pool of different modular nucleic acid tags to form a plurality of doubly-tagged target nucleic acids, amplifying each of the doubly-tagged target nucleic acids, thereby preparing a library of nucleic acids having modular end sequences, and detecting the library of amplified nucleic acids having modular end sequences.
    Type: Grant

  • Publication number: 20250051832
    Abstract: Described herein are methods and compositions for improved hybridization capture for enriching for target nucleic acid sequences from a population of nucleic acids. In one aspect, the methods and compositions are useful for Next Generation Sequencing (NGS) applications. The methods and compositions include combining in solution capture probes and target nucleic acid and permitting hybridization of the target nucleic acid to the capture probes under conditions to promote efficient hybridization. Following hybridization, the probe/target complex is immobilized to a capture material while simultaneously incubating at an optimum hybridization temperature. The incubation denatures unwanted nucleic acids from the capture probes further enriching for target nucleic acid.

  • Patent number: 11898204
    Abstract: The invention is a novel method of separately sequencing each strand of a nucleic acid involving the use of an adaptor comprising a strand cleavage site or a strand synthesis termination site. The adaptor may also be self-priming at the strand cleavage site.
