RESUMO

A simple solid phase method for the synthesis of oligodeoxyribonucleotides has been developed using the phosphotriester approach. Mononucleotide coupling units are sequentially added to the polystyrene copolymer with 1% divinylbenzene and two kinds of oligonucleotides, d(CACGACCCCTCCACGT) and d(AACTGGTATTACTGGGCG), are synthesized in a relatively high yield. One cycle of the mononucleotide addition is about 70 minutes, and this method is particularly suitable for the automation of the synthesis upon availability of an automatic synthesizer.
