Thermostable T7 RNA Polymerase 

Thermostable T7 RNA Polymerase is a thermostable version of T7 RNA Polymerase (HY-E70090). Compared with T7 RNA Polymerase, it has high temperature resistance and stable activity. T7 RNA polymerase is a polymerase expressed by Escherichia coli from the RNA polymerase gene of T7 bacteriophage. T7 RNA polymerase is highly specific and involved in in vitro transcription (IVT) of mRNA. In the presence of Mg²⁺, T7 RNA polymerase only uses the single-stranded or double-stranded DNA containing the T7 promoter sequence as a template, and uses NTP as a substrate to synthesize RNA complementary to the single-stranded DNA downstream of the promoter^[1][2][3].
