Purification of Nucleic Acids by Hybridization to Affinity Tagged PNA Probes

Henrik Ørum

The use of affinity tagged PNA capture probes offers an efficient means for the purification of nucleic acids by hybridization. Two different approaches are described. A sequence specific method and a generic method. The sequence specific method requires sequence information on the target and synthesis of a dedicated PNA. It can be used to selectively purify the nucleic acid containing the target from non-related nucleic acids and other cellular components. The generic method uses a "universal" triplex forming PNA and requires no sequence information on the target. It can be used in the bulk purification of large nucleic acids.
