Transcription
Exceptionally high yields of RNA
transcripts in very short time
The Thermo ScientificTM TranscriptAidTM T7 High Yield Transcription
Kit is designed for high yield in vitro transcription from DNA templates
containing a T7 RNA polymerase promoter and is suitable to
synthesize both short (<100 nt) and long transcripts. Depending on
transcript length each reaction yields approximately 200 µg RNA from
1 µg template DNA in 2 hours. For maximum flexibilty, the kit provides
protocols for the generation of unlabeled, labeled and capped RNA.
Besides all reagents for in vitro transcription, loading dye and a RNA
ladder for gel analysis are included with the kit.
Features
• Exceptionally high
yields – up to 200 µg in
2 hours
• Versatile – suitable for
both short and long RNA
transcripts
• Milligram amounts of
RNA in a single, scaledup reaction
Obtained RNA is of high integrity and can be used in numerous
applications including RNA structural and functional studies,
ribozyme biochemistry, RNase protection assays and hybridizationbased blots, anti-sense RNA and RNAi experiments, microarray
analysis, microinjection, in vitro translation, and RNA vaccines related experiments.
• Flexible – generates
unlabeled, labeled or
capped RNA
• High value –
RNA ladder included
 RNA synthesis by in vitro
transcription using linearized
plasmid DNA as a template.

 RNA transcripts (500 nt, 1000 nt and 6000 nt) were generated using high
yield in vitro transcription reactions containing 1 μg of DNA template. Each
20 μL reaction was incubated for 2 hours at 37°C. The transcription products
were diluted 120-fold and 6 μL was run on a 1% agarose/TAE gel supplemented
with 0.5 μg/mL EtBr.
