  • Publication number: 20240150824
    Abstract: The present disclosure relates to tagged nucleoside-5?-oligophosphates having a positively charged polymer tag structure and components thereof. Such nucleoside-5?-oligophosphates are useful, for example, in nanopore-based sequencing-by-synthesis applications. Also disclosed herein are nanopore constructs engineered to have additional negatively-charged moieties in the channel of the nanopore. Such nanopores can be useful, for example, for providing a repellant force against template and/or primer nucleic acids inserting into the pore during a nucleic sequence-by-synthesis process. The tagged nucleoside-5?-oligophosphates and nanopores disclosed herein can be used together to provide nanopore-based nucleic acid sequencing-by-synthesis systems and processes having reduced background tag levels and improved throughput.

  • Publication number: 20230159999
    Abstract: This application discloses compositions comprising primer compounds that reduce or block deleterious threading into a nanopore of nucleic acid strands displaced by a nanopore-linked polymerase, for example during the use of a nanopore device for nucleic acid sequencing. Also disclosed are methods for using the compositions to reduce deleterious threading events during nanopore-based nucleic acid detection techniques, such as nanopore sequencing.
