title: Solid phase phosphotriester synthesis of large oligodeoxyribonucleotides on a polyamide support.
abstract: Phosphotriester solid phase methodology on a polyamide support [(1980) Nucleic Acids Research, 8, 1081-1096] has been extended for the rapid synthesis of the tetradecanucleotide, d(AGTTGTTTGTAGTT), the octadecanucleotide, d(GTGGGTTTGGGGCAGGTC), and the heneicosanucleotide, d(GTGCTCTTATCCTCTTGGCTC). Thus, oligodeoxyribonucleotides comparable in size to those obtained by solution synthesis are readily accessible using solid phase techniques. An approach to the purification of the synthetic octadecanucleotide without recourse to high performance liquid chromatography is described.
