Artificial transcription elongation compexes are assembled in vitro using synthetic deoxy-oligonucleotides (representing template and non template DNA strands), radiolabelled RNA (representing nascent transcript) and purified RNA polymerase. After high salt wash the incorrect NTP is added and reaction is allowed to proceed for the various amounts of time. Reaction is stopped by addition of formamide-containing loading solution and the products are resolved on high-percentage denaturing polyacryamide gel. Bands are revealed by PhosphoImaging (GE Healthcare) and analysed using ImageQuant software (GE Healthcare).
