A solid support for oligonucleotide synthesis has the structure ##STR1## where CPG represents a controlled pore glass matrix, the wavy line represents a carbon chain covalently linking the NH group with the controlled pore glass matrix, X is 2,2'-dimethoxytrityl or H, and R is alkyl, aryl, arylalkyl, heteroalkyl, or heteroaryl. The dimethoxytrityl group is removed from the solid support by treatment with acid, and the oligonucleotide is built, step-by-step in a conventional synthesizer after attachment of the 3' end of the first oligonucleotide unit to the hydroxyl function connected to the R group.
寡核苷酸合成的固体支持物具有以下结构:##STR1## 其中CPG代表受控孔玻璃基质,波浪线代表将NH基与受控孔玻璃基质共价连接的碳链,X为2,2'-二甲氧基三苯甲基或H,R为烷基,芳基,芳基烷基,杂原子烷基或杂原子芳基。通过酸处理从固体支持物中去除二甲氧基三苯甲基基团,并在将第一个寡核苷酸单元的3'端连接到连接到R基团的羟基功能后,在传统合成器中逐步构建寡核苷酸。
