Abstract

Initiator nucleotides consisting of an anthracene ring system coupled to the 5'-phosphate of guanosine monophosphate via a polyethylene glycol (PEG) linker were chemically synthesized. When added to transcription reactions, these initiators were site-specifically incorporated into RNA transcripts yielding RNA conjugates with a fluorophore selectively attached to the 5'- end via a flexible linker. Besides sensitive fluorescence detection, the anthracene allowed the convenient modification with maleimides by Dieis- Alder reaction.
