A process for synthesizing an oligonucleotide comprising linking a nucleoside phosphate to a solid support, through the heterocyclic moiety of the nucleoside, coupling a mono-or oligonucleotide to the nucleoside phosphate through its phosphate moiety, in at least one step enzymatically lengthening the mono- or oligonucleotide, cleaving the resultant oligonucleotide from the solid support-nucleoside phosphate at the phosphate moiety of the nucleoside, and separating the oligonucleotide. After cleaving and separating the solid support-nucleoside phosphate is recycled for further coupling. Advantageously the solid support-nucleoside phosphate is phosphorylated between separation and recycling.
一种合成寡核苷酸的工艺,包括通过核苷的杂环分子将核苷磷酸酯连接到固体支持物上,通过核苷磷酸酯的磷酸分子将单核或寡核苷酸偶联到核苷磷酸酯上、在至少一个步骤中酶切延长单核苷酸或寡核苷酸,在核苷酸的磷酸基上从固体支持物-核苷酸磷酸酯上裂解产生的寡核苷酸,并分离寡核苷酸。在裂解和分离后,固体支持物-核苷磷酸酯被回收用于进一步偶联。有利的是,在分离和回收之间,固体支持物-核苷磷酸会被磷酸化。
