摘要: 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.

摘要: The present disclosure provides methods and reagents for improving nanopore-based analyses of polymers. Specifically, the disclosure provides a method of analyzing a polymer that includes a polymer analyte that contains an end domain that has at least one charged moiety. The disclosure also provides a method of increasing the interaction rate between a polymer analyte and a nanopore, wherein the polymer analyte contains an end domain that has at least one charged moiety. The disclosure also provide compositions for use with the described methods, including adapter compositions that contain charged moieties, such as phosphate or sulfate groups, and that are configured to being linked to an polymer analyte domain.

摘要: Provided herein are methods and systems pertaining to sequencing units of analytes using nanopores. In general, arresting constructs are used to modify an analyte such that the modified analyte pauses in the opening of a nanopore. During such a pause, an ion current level is obtained that corresponds to a unit of the analyte. After altering the modified analyte such that the modified analyte advances through the opening, another arresting construct again pauses the analyte, allowing for a second ion current level to be obtained that represents a second unit of the analyte. This process may be repeated until each unit of the analyte is sequenced. Systems for performing such methods are also disclosed.

摘要: 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.
