The invention features linker molecules that have at one terminus a amino-protecting group and at the other terminus a phosphorous activating group, typically phosphoramidite. The linker molecules can be used, for example, to produce amino-modified linkers that space an oligonucleotide from a solid support. The invention also features an amino-protected nucleotide that includes an activated phosphorous group such as a phosphoramidite for the production of a 5′ amino-modified oligonucleotide. The invention further provides a phthalimido-modified support that can be used to synthesize a polynucleotide that includes an amino group at the 3′ terminus.
该发明涉及连接分子,其在一个端部具有氨基保护基团,在另一个端部具有磷活化基团,通常为磷酰胺基。例如,可以使用连接分子来产生氨基修饰的连接物,将寡核苷酸与固体支持物隔开。该发明还涉及一种氨基保护核苷酸,包括一个活化的磷基团,例如磷酰胺基,用于制备5'氨基修饰的寡核苷酸。该发明还提供了一种邻苯二甲酰亚胺修饰的支持物,可用于合成在3'端具有氨基基团的多核苷酸。
