SP6 RNA Polymerase is a DNA-dependent RNA polymerase that exhibits a high specificity for bacteriophage SP6 promoter sequences. The enzyme can incorporate labeled or unlabeled nucleotide triphosphates into an RNA transcript. Large quantities of RNA can be synthesized from a DNA sequence cloned downstream from an SP6 promoter. SP6 RNA Polymerase is supplied in 10 mM potassium phosphate (pH 7.9), 150mM NaCl, 1 mM DTT, 0.1 mM EDTA and 50% glycerol.
Recombinant E. coli
–20°C
One unit is defined as the amount of enzyme required to incorporate 1 nmol of [3H] GMP into acid-insoluble product in 1 hour at 37°C and pH 7.5 using a linear DNA template.
Supplied with 10X Reaction Buffer [400 mM Tris-HCl (pH 7.5), 60 mM MgCl2, 20 mM spermidine, 100 mM DTT, 0.1 BSA].
