Conjugation of ligands to DNA oligonucleotides has been achieved in the solid phase by strain-promoted azide-alkyne cycloaddition (SPAAC). The oligonucleotide, modified with a simple nonfluroinated, monocyclic octyne, efficiently forms conjugates with a range of azide dipoles with varying steric and electronic characteristics. The reaction is clean and easily executed in a copper free environment at
通过应变促进的叠氮化物-炔环加成 (SPAAC) 在固相中实现了配体与 DNA 寡核苷酸的缀合。用简单的非氟化单环辛炔修饰的寡核苷酸有效地与一系列具有不同空间和电子特性的叠氮偶极子形成共轭物。该反应在室温下无铜环境中干净且容易进行。它提供了多种三唑连接的核酸偶联物,可用于生物技术和细胞生物学。
