ENZYME METHOD

摘要

The invention relates to a new method of characterising a target polynucleotide. The method uses a pore and a Hel308 helicase or amolecular motor which is capable of binding to the target polynucleotide at an internal nucleotide. The helicase or molecular motor controls the movement of the target polynucleotide through the pore.

主权项

1. A method of characterising a target polynucleotide, comprising:
(a) contacting the target polynucleotide with a transmembrane pore and a Hel308 helicase such that the helicase controls the movement of the target polynucleotide through the pore and nucleotides in the target polynucleotide interact with the pore; and (b) measuring one or more characteristics of the target polynucleotide during one or more interactions and thereby characterising the target polynucleotide.
