T7 RNA Polymerase is a DNA-dependent RNA polymerase derived from the T7 bacteriophage which exhibits a high recognition specificity to the T7 promoter and terminator sequences and catalyzes the 5' -> 3' synthesis of RNA starting at a T7 promoter sequence(1,2).

Specific Activity: 312,500 U/mg

- Radiolabeled RNA probe preparation
- RNA generation for in vitro translation
- RNA generation for studies of RNA structure, processing and catalysis
- Expression control via anti-sense RNA

Purified from a strain of E. coli that expresses the recombinant T7 RNA Polymerase gene.
