T7 RNA Polymerase

Bacteriophage T7 RNA Polymerase is a DNA-dependent RNA polymerase with strict specificity for the T7 phage promoter. The enzyme is widely used for the synthesis of specific transcripts from DNA in the 5'→ 3' direction, as well as being a suitable model for studying the mechanisms of transcription. The RNA produced by T7 RNA Polymerase is suitable for many downstream applications. GenScript is offering T7 RNA Polymerase produced by expression in an E. coli strain carrying a plasmid encoding the T7 RNA Polymerase.
