Product Description
This product is a bacteriophage T7 RNA polymerase derived from recombinant expression in E. coli. It is a T7 RNA polymerase obtained by mutation after modification and optimization of wild-type T7, which can significantly reduce the dsRNA content. Double-stranded DNA containing the T7 promoter sequence is used as a template and NTP is used as a substrate to synthesize RNA complementary to the reverse single-stranded DNA downstream of the promoter. Double-stranded linear blunt-end or 5' protruding end DNA can be used as a substrate template for T7 RNA polymerase, so linear plasmids and PCR products can be used as templates for in vitro RNA synthesis.

Reactions were carried out in a 20 µL system at 27 °C for 2 h using different T7 enzymes. RNA yield remained stable as cap analog input decreased, while integrity and capping efficiency showed a gradual decline. A cap analog concentration of ≥2.5 mM is recommended for optimal performance.
