We present a screening assay based on fluorescence readout for the directed evolution of T7 RNA polymerase variants with acceptance of 2'-modified nucleotides. By using this screening we were able to identify a T7 RNA polymerase mutant with increased acceptance of 2'-methylseleno-2'-deoxyuridine 5'-triphosphate.
