Bacteriophage SP6 RNA polymerase is a DNA-dependent RNA polymerase with strict specificity for the SP6 phage promoter. It seems that morphology and development of phage SP6 are similar to those of E.coli phage T7. Like T7 RNA Polymerase, the SP6 RNA Polymerase is also widely used for the synthesis of specific transcripts, as well as being a suitable model for studying the mechanisms of transcription. The RNA produced by SP6 RNA Polymerase is suitable for many downstream applications. GenScript is offering SP6 RNA Polymerase produced by expression in an E. coli strain carrying a plasmid encoding the SP6 RNA Polymerase. "

Bacteriophage SP6 RNA polymerase is a DNA-dependent RNA polymerase with high affinity and specificity for SP6 phage promoter, limiting the SP6 RNA synthesis to DNA cloned downstream of an SP6 promoter.. Like T7 RNA Polymerase, the SP6 RNA Polymerase is also widely used for the synthesis of specific transcripts, as well as being a suitable model for studying the mechanisms of transcription. The RNA produced by SP6 RNA Polymerase is catalyzed from 5’à3’ and is suitable for many downstream applications.
GenScript is offering SP6 RNA Polymerase produced by expression in an E. coli strain carrying a plasmid encoding the SP6 RNA Polymerase. 

For laboratory research use only. Direct human use, including taking orally and injection and clinical use are forbidden.
