The invention features protected linker compounds which comprise at one terminus a protected amino group and at another other terminus a phosphorous activating group, such as a phosphoramidite group. These protected linker compounds are introduced chemically at the 5'-end of oligonucleotides for the purpose of preparing 5'-amino modified oligonucleotides. After deprotection, the thereby introduced amino group then allows further modification (e.g. attachment of dyes) or immobilization (on surfaces or beads) of the oligonucleotide. Specifically, the presented amino protecting group is designed to provide such protected linker compounds in a solid form, which facilitates efficient purification by precipitation or crystallization and aliquoting for distribution and storage.
该发明涉及一种保护链连接物,其在一个端部具有保护的氨基基团,在另一个端部具有磷酸化活性基团,例如磷酰胺基基团。这些保护链连接物在化学上被引入到寡核苷酸的5'-端,以制备5'-氨基修饰的寡核苷酸。去保护后,引入的氨基基团允许进一步修饰(例如附着染料)或固定(在表面或珠子上)寡核苷酸。具体而言,所提供的氨基保护基团旨在以固体形式提供这些保护链连接物,从而通过沉淀或结晶实现高效纯化和分配存储。
