T7 RNA Polymerase

$ 70.00

T7 RNA Polymerase is a DNA-dependent RNA polymerase that exhibits high specificity for its cognate promoter sequence 5'-TAATACGACTCACTATA-3'. The enzyme can incorporate labeled or unlabeled nucleoside triphosphates into an RNA transcript from a DNA sequence cloned downstream of the T7 promoter.  


  • Synthesis of mRNA for in vitro translation.
  • Synthesis of guide RNA.
  • Generation of antisense RNA.
  • Generation of probes for nucleic acid hybridizations.

Storage buffer: 40 mM Tris-HCl (pH 7.9 at 25°C), 100 mM NaCl, 1 mM DTT, 0.1 mM EDTA, 0.1% (v/v) Triton® X-100 and 50% glycerol.

The enzyme is supplied with 10X T7 RNA Polymerase Buffer (400 mM Tris-HCl, pH 7.9, 60 mM MgCl2, 100 mM Dithiothreitol, 20 mM Spermidine).

Catalog number: T7RP-301
