Principles and methods for the analysis and purification of synthetic deoxyribonucleotides by high-performance liquid chromatography.

The need for high-purity oligodeoxyribonucleotides for various applications has resulted in the development of novel synthesis, purification, and analytical techniques. A diversity of methods, including polyacrylamide slab gel electrophoresis, capillary gel electrophoresis, as well as high-performance liquid chromatography (HPLC), have been successfully used to aid in the characterization and isolation of these synthetic compounds. The information contained in this review article primarily details both the theoretical and practical aspects related to the use of HPLC for the analysis and purification of synthetic DNA. In addition, a variety of postsynthesis sample preparation protocols, commonly employed prior to and after HPLC, are described.
