The set consists of 100 mM aqueous solutions of ATP, CTP, GTP and UTP each supplied in a separate vial. Since the ribonucleotides are provided separately, the NTP Set offers maximum flexibility in preparation of reaction mixes for different applications. It is suitable for in vitro transcription reactions with SP6, T3, and T7 RNA polymerases for the production of RNA probes or transcripts for in vitro translation.
