Universal supports for oligonucleotide synthesis include a support material represented by the following formula:
1
In this formula, substituent A is selected from H, alkyl, aryl, or a polymeric or silica base material; substituent B is selected from acyl, aroyl, or a polymeric or silica base material; and substituent C is selected from a dimethoxytrityl group or a protecting group removable under acidic or neutral conditions. For the supports, one of substituents A or B constitutes the polymeric or silica base material. In use, an oligonucleotide is attached to the support at substituent C.
通用寡核苷酸合成支持材料的公式如下所示:1在该公式中,取代基A选自H、烷基、芳基或聚合物或
硅基材料;取代基B选自酰基、芳酰基或聚合物或
硅基材料;取代基C选自二甲氧基三苯甲基基团或在酸性或中性条件下可去除的保护基团。对于这些支持材料,取代基A或B之一构成聚合物或
硅基材料。在使用中,寡核苷酸被连接到取代基C上。
