  • Patent number: 10612083
    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: 20170227494
    Abstract: 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.

  • Patent number: 8999716
    Abstract: Provided herein are artificial membranes of mycolic acids. The membranes may be unsupported or tethered. These membranes are long lived and highly resistant to electroporation, demonstrating their general strength. The mycolic acid membranes are suitable for controlled studies of the mycobacterial outer membrane and can be used in other experiments, such as nanopore analyte translocation experiments.
