Labeled oligonucleotides, methods for making same, and compounds useful therefor

摘要

Selectively functionalized oligonucleotides, methods for making same, and compounds useful therefor are disclosed. The oligonucleotides can be selectively functionalized with a first conjugate group at the 3'-terminial position and optionally functionalized with a second conjugate group at the 5'-terminal position and/or one or more internucleotides. Alternatively, the oligonucleotides can be selectively functionalized with a first conjugate group at the 5'-terminal position and optionally functionalized with a second conjugate group at one or more internucleotides. In yet another embodiment, the oligonucleotides can be functionalized with a first conjugate group at one or more internucleotides and with a second conjugate group at one or more different internucleotides.
