T7 RNA Polymerase (MB080)

Refrigerated package


Description: T7 RNA polymerase is a recombinant enzyme purified from Escherichia coli, for the synthesis of highly specific activity RNA probes, biologically active mRNA and antisense RNA. T7 RNA polymerase is DNA-dependent with strict specificity for its own double-stranded promoter that is not efficiently recognized by SP6 or T3 RNA polymerases. T7 RNA polymerase catalyzes the 5’→3’ synthesis of RNA from ribonucleoside triphosphates on single or double stranded DNA downstream from a T7 promoter. Using circular plasmid DNA as a template will result in heterogeneous transcripts of multiple lengths. T7 RNA polymerase accepts modified nucleotides as substrates for RNA synthesis.

– Quick and easy production of RNA transcripts from DNA template containing a RNA polymerase promotor
– Convenient and reliable
– Incorporates modified nucleotides as substrates for RNA synthesis


– Synthesis of RNA transcripts, biologically active mRNA and antisense RNA
– Production of RNA for in vitro translation and gene expression studies
– Generation of labelled RNA probes


Specificity: Highly promoter-specific. Only transcribes DNA cloned downstream of T7 promoter
Optimal reaction temperature: 37 ºC
Denaturing conditions:  T7 RNA polymerase can be inactivated by adding 20 mM EDTA (pH 8.0) final concentration or by heating at 70 °C for 10 min
Storage conditions: Store at -20 ºC
Shipping conditions: Shipped at 4 ºC to dry ice

– T7 RNA Polymerase (20 U/μL or 200 U/μL)
– Reaction Buffer (10x)
