New tags and an encoding strategy for combinatorial synthesis are described. Combinatorial libraries of short oligonucleotides attached to TentaGel beads were synthesised by a split-and-mix strategy using 5′-DMTr or 5′-Fmoc-protected nucleoside phosphoramidites. Trityl moieties with different masses were used to tag the nature and position of monomer units (bases) coupled at each step in the synthesis
描述了用于组合合成的新标签和编码策略。使用5'-DMTr或5'-Fmoc保护的核苷亚磷酰胺通过拆分混合策略合成了连接到TentaGel珠的短寡核苷酸的组合文库。使用具有不同质量的三苯甲基部分标记在合成的每个步骤中偶联的单体单元(碱基)的性质和位置。通过杂交从组合文库中选择具有特定寡核苷酸的珠。通过将不同分子量的胺偶联到三苯甲基部分上的一个或多个活化的羧基上来产生与添加的核苷酸正交的标签。可以通过酸性处理或激光照射将标签从支持物上释放,然后通过(MA)LDI-TOF进行分析。
