Abstract: A composition and method of cleaving a target DNA and isolating a DNA sequence of interest, directed by a targeting oligonucleotide (“ON”) including a DNA binding agent (stable or unstable), is disclosed. The targeting ON binds to the target DNA before or during DNA cleavage. After cleavage, the isolation of the DNA fragment of interest is facilitated by the affinity tag on the targeting ON or an affinity tag attached using either ligation or polymerase extension method.

Abstract: By using engineered sequence specific DNA nuclease (“SSDN”), the composition, reagent kit and method of the present invention can cut and release a DNA sequence of interest 1×104-1×107-base pairs long from a source DNA as large as the whole genome. The SSDN further includes an affinity tag or is bound to a solid support that facilitates the isolation of the DNA sequence of interest. The SSDN can include a RecA and Ref combination, a transcription activator like effector nuclease, or a sequence specific chemical nuclease. When applied to genomic sequencing, specific region(s) of interest in the genome can be cut and isolated. Because the irrelevant part of the genome is removed from the sequencing reaction, the speed, cost, and accuracy of genomic sequencing can be improved.
