Peptide nucleic acids (PNAs) have now existed for slightly more than ten years, with the interest in and applications of this pseudopeptide DNA mimic steadily increasing during the entire period. PNAs have rapidly attracted the attention of scientists from a diversity of fields ranging from (bio)organic and biophysical chemistry to prebiotic evolution, and from molecular biology to genetic diagnostics and drug development. Many of the applications take advantage of the unique properties of PNA-an uncharged pseudopeptide-that distinguish this DNA mimic from more traditional DNA analogs. Rather than trying to create a comprehensive collection of all published methods and protocols involving PNA-many of which have not yet been validated- I have decided to concentrate on select protocols that are either very well established by several groups around the world, such as PCR-clamping and in situ hybridization, or on new methods that may have broader future impact. Basic methods for PNA oligomer synthesis and analyses have also been included. I am very grateful to those friends and colleagues who have enthusiastically contributed their work, discussions, and writing, and thereby made this book possible. Peter E.

Peptide nucleic acid (PNA) technology continues to grow in importance throughout molecular biology, genetic diagnostics, and molecular medicine. In Peptide Nucleic Acids: Methods and Protocols, Peter Eigil Nielsen has assembled a critically evaluated collection of PNA protocols that are either already well established around the world, such as PCR-clamping and in situ hybridization, or that display promise of significant future impact. Basic methods for PNA oligomer synthesis and analysis have also been included. Written by experts with hands-on experience in the methods they describe, these readily reproducible protocols contain detailed step-by-step instructions, tips on avoiding pitfalls and on extending the method to other situations, and introductory material explaining the theory behind the process. Uptodate and highly practical, Peptide Nucleic Acids: Methods and Protocols provides for both novice and experienced researchers a thorough and easy introduction to the optimal use of today's PNA technology across a wide variety of fields, including molecular biology, medicinal chemistry, genetic diagnostics, and drug development.
