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.
固体支持物质用于寡核苷酸合成具有以下结构##STR1##其中CPG代表受控孔玻璃基质,波浪线代表碳链与受控孔玻璃基质中的NH基共价连接,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。二甲氧基三苯甲基基团通过酸处理从固体支持物质中去除,然后在将第一个寡核苷酸单元的3'末端连接到与R基团相连的羟基功能后,通过传统合成器逐步构建寡核苷酸。
