NxGen® T7 RNA Polymerase
NxGen® T7 RNA Polymerase
-
Reliable transcription.
T7 RNA Polymerase catalyzes the 5′→3′ RNA synthesis from the T7 promoter. It is a DNA-dependent RNA polymerase cloned from the T7 bacteriophage, which recognizes the T7 promoter and terminator sequences with high specificity.
