title: Rapid synthesis of oligodeoxyribonucleotides: a new solid-phase method.
abstract: A method is described that makes use of a new polyamide resin for the rapid synthesis of short oligodeoxyribonucleotides. The method is illustrated by the preparation of two heptadeoxyribonucleotides, d(pT6-C) and d(pC-A-G-T-G-A-T) using a phosphodiester approach. A further development involved use of phenyl isocyanate as an in situ drying agent, which obviated the need for solvent co-evaporation prior tothe internucleotidic coupling steps. Improved fractionation of thymidyl oligonucleotides was obtained by use of a new microparticulate, silica-based anion-exchanger.
