T7 RNA Polymerase


T7 RNA Polymerase is useful for sgRNA and mRNA synthesis, RNA synthesis from DNA templates and applications in mRNA therapeutics

    25,000 Units - $149.00 (Cat.# 3723 )


Intact Genomics Bacteriophage T7 RNA Polymerase is a DNA-dependent RNA polymerase that is highly specific for the bacteriophage T7 promoter and terminator sequences. T7 RNA Polymerase catalyzes in vitro RNA synthesis in a 5’→3′ direction from a cloned DNA sequence under the T7 promoters. The enzyme can incorporate labeled or unlabeled nucleotide triphosphates into an RNA transcript.
