TranscriptAid T7 High Yield Transcription Kit is designed to produce both long and short transcripts for applications that require large yields of RNA (milligram amounts). The kit can achieve 10 times greater amount than from conventional in vitro transcription reactions with T7 RNA polymerase due to its unique proprietary enzyme and buffer formulations. Please note that TranscriptAid T7 High Yield Transcription Kit is not recommended for generation of radioactively labelled RNA. Due to large quantities of RNA synthesized with the kit, generation of high specific activity radiolabeled probes would require prohibitively large amounts of radiolabeled nucleotide.
