Abstract
A method of separating a target double-stranded nucleic acid molecule from a sample including the target double-stranded nucleic acid molecule and a non-target double-stranded nucleic acid molecule, including (1) mixing the sample, a pyrrole-imidazole-containing polyamide (first PI polyamide) modified with a first linker molecule and capable of specifically binding to a sequence of the target double-stranded nucleic acid molecule, and a carrier a modified with a first ligand capable of specifically binding and/or adsorbing to the first linker molecule such that a mixed solution is produced, (2) forming a complex A by binding the carrier a to the first PI polyamide with which the target double-stranded nucleic acid molecule is bound in the mixed solution, and (3) separating the complex A from the mixed solution.
