Product information
T7 RNA Polymerase catalyses the 5′→3′ RNA synthesis from the T7 promoter. It is a DNA-dependent RNA polymerase cloned from the T7 bacteriophage, which recognises the T7 promoter and terminator sequences with high specificity.
Unit Definition: One unit is defined as the amount of enzyme that will incorporate 1 nmol of ATP into acid-precipitable material in 1 hour at 37 °C.
Source: Purified from a strain of E. coli that expresses the recombinant T7 RNA Polymerase gene.
