Perspectives on analyses of nucleic acid constituents: The basis of genomics

Document Type


Date of Original Version



The recent mapping of the human genome was a tremendous achievement made possible to a large degree by the development of analytical methods for sequencing purine and pyrimidine bases in nucleic acids. In the last 3 decades, the number of analyses of nucleic acids and their constituents by HPLC and capillary electrophoresis (CE) has exploded. These techniques have been used not only for genomics, but also for the determination of free nucleotides, nucleosides and their bases in body fluids and tissues. Although a large number of HPLC and CE papers have been published on nucleic acid constituent applications, relatively little has been written on the mechanisms of the separations. However, to optimize analytical conditions knowledgeably and rapidly, it is important to know why and how these separations occur and the factors that affect them. The HPLC methods for the analysis of nucleic acid constituents and the information available on some of the mechanisms of separation of nucleotides, nucleosides and their bases, as well as the analysis of these compounds by CE and the factors that affect these separations are discussed. © 2002 Elsevier Science B.V.
