T7 RNA polymerase

T7 RNA polymerase is used to produce mRNA in vitro and in vivo. It binds to a T7 RNA polymerase promoter, a DNA sequence which can be attached to any DNA molecule to produce any polypeptide. It is extensively used in prokaryotic and eukaryotic transcription-translation reactions in vitro for protein production. 

T7 RNA polymerase is purified from E. coli which contains T7 RNA polymerase (6xHIS) expressing plasmid.
