A method of modulation of synthesis capacity on and cleavage properties of synthetic oligomers from solid support is described. The method utilizes linker molecules attached to a solid surface and co-coupling agents that have similar reactivities to the coupling compounds with the surface functional groups. The preferred linker molecules provide an increased density of polymers and more resistance to cleavage from the support surface. The method is particularly useful for synthesis of oligonucleotides, oligonucleotides microarrays, peptides, and peptide microarrays. The stable linkers are also coupled to anchor molecules for synthesis of DNA oligonucleotides using on support purification, eliminating time-consuming chromatography and metal cation presence. Oligonucleotides thus obtained can be directly used for mass analysis, DNA amplification and ligation, hybridization, and many other applications.
本文介绍了一种调节固体支持物上合成低聚物的合成能力和裂解特性的方法。该方法利用附着在固体表面的连接分子和与表面官能团偶联化合物具有相似反应活性的助偶联剂。优选的连接分子可增加聚合物的密度,提高从支撑表面裂解的阻力。该方法尤其适用于合成寡核苷酸、寡核苷酸微阵列、肽和肽微阵列。这种稳定的连接体还可与锚分子偶联,用于合成 DNA 寡核苷酸,在支持物上进行纯化,省去了耗时的色谱法和金属阳离子的存在。由此获得的寡核苷酸可直接用于质量分析、DNA 扩增和连接、杂交以及许多其他应用。
