Enzymatic synthesis and reverse transcription of RNAs incorporating 2′-O-carbamoyl uridine triphosphate

Enzymatic synthesis and the reverse transcription of RNAs containing 2'-O-carbamoyl uridine were evaluated. A mild acidic deprotection procedure allowed the synthesis of 2'-O-carbamoyl uridine triphosphate (UcmTP). UcmTP was incorporated correctly into long RNAs, and its fidelity during reverse transcription using SuperScript III was sufficient for RNA aptamer selection.
