WebMay 18, 2015 · While using modified bases expands the chemical functionality of DNA, a single phosphorothioate modification might boost its affinity for thiophilic metals without complicating the selection process or using bases that are not commercially available. In this work, the first such in vitro selection for Cd 2+ is reported. WebPhosphorothioate. Phosphorothioate modification is to the backbone linkage modifying the phosphodiester linkage to phosphorothioate. This imparts considerable nuclease resistance and is used widely in the design of antisense oligonucleotides (ODN). ... Methyl phosphonoamidites are deoxynucleoside amidites modified such that, when incorporated ...
