Patent attributes
The invention relates to devices and methods for nanopore sequencing. Methods for controlling translocation of through the nanopore are disclosed. The rate of transport of the template nucleic acids through the nanopore can be controlled using a translocating enzyme having two slow kinetic steps. The translocating enzyme and reaction conditions can be selected such that the translocating enzyme exhibits two kinetic steps wherein each of the kinetic steps has a rate constant, and the ratio of the rate constants of the kinetic steps is from 10:1 to 1:10. The invention also provides for using the signals from n-mers to provide sequence information, for example where the system has less than single base resolution. The invention includes arrays of nanopores having incorporated electronic circuits, for example, in CMOS.
