Abstract:
This protocol describes the synthesis and purification of RNAs using plasmid DNA or PCR-amplified DNA as a template. This procedure should give NTP-free, full-length RNA for all sizes of RNA. This protocol is derived from Milligan and Uhlenbeck, the classic paper on T7 transcription reactions, with modifications.
