In biotechnology applications, T7 RNA polymerase is commonly used to transcribe DNA that has been cloned into vectors that have two (different) phage promoters (e.g., T7 and T3, or T7 and SP6) in opposite orientation. RNA can be selectively synthesized from either strand of the insert DNA with the different polymerases.

Bacteriophage T7 RNA Polymerase is a DNA-dependent RNA polymerase that is highly specific for the T7 phage promoters. The 99 KD enzyme catalyzes in vitro RNA synthesis from a cloned DNA sequence under the T7 promoters. RNA produced using the T7 RNA Polymerase is suitable for many applications in research and biotechnology.

T7 RNA Polymerase is a DNA-dependent RNA polymerase that exhibits extremely high specificity for its cognate promoter sequences. Only T7 DNA or DNA cloned downstream from a T7 promoter can serve as a template for T7 RNA Polymerase-directed RNA synthesis.

Hi-T7 RNA Polymerase is an engineered DNA-dependent RNA polymerase that is highly specific for T7 phage promoters and is designed to function at higher temperatures than the wild-type bacteriophage T7 RNA Polymerase. Hi-T7 RNA Polymerase functions at an optimal temperature of 50-52°C.

T7 DNA polymerase is an enzyme used during the DNA replication of the T7 bacteriophage.During this process, the DNA polymerase “reads” existing DNA strands and creates two new strands that match the existing ones. The T7 DNA polymerase requires a host factor, E. coli thioredoxin, in order to carry out its function. This helps stabilize the binding of the necessary protein to the primer ...

T7 RNA Polymerase is a DNA-dependent RNA polymerase that exhibits a high specificity for bacteriophage T7 promoter sequences. The enzyme can incorporate labeled or unlabeled nucleotide triphosphates into an RNA transcript. Large quantities of RNA can be synthesized from a DNA sequence cloned downstream from a T7 promoter. T7 RNA Polymerase is ...

T7 RNA polymerase is a member of a family of single-subunit RNAPs that includes the phage RNAPs (T3, K11, SP6, N4, and others) as well as the mitochondrial RNAPs (McAllister, 1993a,b). Within this family of enzymes, the greatest divergence always occurs in the N-terminal domains.

T7 RNA polymerase is commonly used to transcribe DNA which has been cloned into vectors which have two phage promoters in opposite orientation. RNA can be selectively synthesized from either strand of the insert DNA with different polymerases. Homogeneously labeled single-stranded RNA can be generated with this system.
