Solid-phase synthesis of selectively labeled DNA: applications for multidimensional nuclear magnetic resonance spectroscopy.

The solid-phase chemical synthesis method has a strong advantage over the enzymatic method for preparing selectively labeled DNA oligomers. Atom-specific and fully labeled 2'-deoxynucleosides are economically prepared with routinely available isotope precursors using this synthetic route. Special DNA oligomers prepared by advanced labeling techniques are needed for advanced NMR applications, and chemical synthesis is the method of choice to respond to such demands. As a summary of this chapter, two tables are given. Table I lists the labeled nucleosides reported to be available by chemical syntheses. Table II lists the NMR studies using labeled DNA oligomers that were prepared by chemical syntheses.
