T7 RNA Polymerase
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.
