  • 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.

  • Publication number: 20210032695
    Abstract: The present disclosure provides method and systems for improving nanopore-based analyses of polymers. The disclosure provides methods for selectively modifying one or more monomeric subunit(s) of a kind a pre-analyte polymer that results polymer analyte with a modified subunit. The polymer analyte produces a detectable signal in a nanopore-based system. The detectable signal, and/or its deviation from a reference signal, indicates the location of the modified subunit in the polymer analyte and, thus, permits the identification of the subunit at that location in the original pre-analyte polymer.
