  • Patent number: 11788132
    Abstract: Techniques for measuring sequences of nucleic acids are provided. Time-based measurements (e.g., forming a histogram) particular to a given sequencing cell can be used to generate a tailored model. The model can include probability functions, each corresponding to different states (e.g., different states of a nanopore). Such probability functions can be fit to a histogram of measurements obtained for that cell. The probability functions can be updated over a sequencing run of the nucleic acid so that drifts in physical properties of the sequencing cell can be compensated. A hidden Markov model can use such probability functions as emission probabilities for determining the most likely nucleotide states over time. For sequencing cells involving a polymerase, a 2-state classification between bound and unbound states of the polymerase can be performed. The bound regions can be further analyzed by a second classifier to distinguish between states corresponding to different bound nucleotides.

  • Patent number: 11768174
    Abstract: To sense the translocation of a molecule through a nanopore, there is directed to an inlet of the nanopore, having a nanopore fluidic resistance, RP, a molecule disposed in a cis fluidic ionic solution having a cis fluidic access resistance, RC. The molecule is caused to translocate through the nanopore from the inlet of the nanopore to an outlet of the nanopore and to a trans fluidic ionic solution having a trans fluidic access resistance, RT. The trans fluidic access resistance, RT, is of the same order of magnitude as the nanopore fluidic resistance, RP, and both RT and RP are at least an order of magnitude greater than the cis fluidic access resistance, RC. An indication of local electrical potential is produced at a site within the nanopore sensor that is on the trans fluidic ionic solution-side of the nanopore, to sense translocation of the molecule through the nanopore.
