SP6 RNA Polymerase
SP6 RNA Polymerase is a DNA-dependent RNA polymerase that exhibits high specificity for the bacteriophage SP6 promoter sequence 5'-TAATCCACTGTGATAT-3'. The enzyme can incorporate labeled or unlabeled ribonucleoside triphosphates into an RNA transcript. Large quantities of RNA can be synthesized from a DNA sequence cloned downstream of the SP6 promoter due to the high processivity of SP6 RNA Polymerase. The enzyme is supplied in a buffer consisting of 10 mM potassium phosphate (pH 7.9), 150 mM NaCl, 1 mM DTT, 0.1 mM EDTA and 50% glycerol.
- In vitro transcription
Supplied with 10X Reaction Buffer [400 mM Tris-HCl (pH 7.5), 60 mM MgCl2, 20 mM spermidine, 100 mM DTT, 0.1% BSA].
