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